FORCE AND MOTION
PART 1: ANSWER ALL THE QUESTIONS
A. When an object is at rest, are any forces acting on it? Explain using Newton´s laws of motion.
There are usually two forces acting on an object at rest, however if the two forces balance each other and the object is at equilibrium, I can say there is no unbalanced force acting upon it and thus this maintains its state of motion.
Based on my research I can say that the behavior of all objects can be described by saying that objects tend to keep on doing what they're doing, it means, if the objects are at rest, they continue at rest, but if they are in motion for example at a velocity of 10 m/s, they will continue in motion. Any state of motion of an object is maintained as long as the object is not acted upon by an unbalanced force. All objects resist changes in their state of motion because they tend to keep on doing what they're doing.

Inertia is proportional to a body's mass, or the amount of matter that a body has. The more mass a body has, the more inertia it has.
B. Describe is there any gravity in outer space?
I found through different texts and articles that there is gravity everywhere, which gives shape to the orbits of the planets, the solar system, and even galaxies. Gravity from the Sun reaches throughout the solar system and beyond, keeping the planets in their orbits. Gravity from Earth keeps the Moon and human-made satellites in orbit.
It is true that gravity decreases with distance, so it is possible to be far away from a planet or star and feel less gravity. That is why many people say there is not gravity in the moon for example, but they are wrong due to the moon is very far from the Earth but has microgravity.
C. Are speed, velocity and acceleration the same thing? Describe by using some examples how you relate these to our daily
There are many theories that all the planets and other space rocks in the solar system orbit around the sun and follow the orbiting route due to the sun’s gravitational force keeping them in course. According to Sir Isaac Newton’s first law “An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” This law is often called "the law of inertia". This is why these planets don’t go severely of course due to the consistent gravitational field the sun is providing. The Kuiper belt and the Asteroid belt are where most of the space rocks, also known as asteroids; orbit along and many stay together because they are part of the s...
Inertia effects acceleration because inertia is the tendency of objects to ether stay at rest or stay in motion. In this case since the point is to move we are more concerned about staying at rest. When starting the dogs have to pull harder to get the sled moving then they do to keep it moving to both overcome the effects of inertia and to change the fiction from static friction to kinetic friction.
4. How would you explain your results using the terms: impulse, momentum, force, and time? Use equations to help you explain the results.
Newton’s second law states that when a net force is applied to an object, that object will experience a change in velocity, and will undergo acceleration. That acceleration is proportional to the net force applied, and inversely proportional to the mass of the object. In other words, the heavier an object is, it will require a greater force to move the object the same amount (e.g., distance) as a lighter object. ( https://www.grc.nasa.gov/www/k-12/airplane/newton2.html)The mathematical equation that expresses Newton’s second law is:
Isaac Newton discovered gravity when an apple had fallen on his head. He then began to think about how the apple had fallen onto his head and thus Newton’s three laws of motion were created. Newton’s first law of motion is an object in motion tends to stay in motion; an object at rest tends to stay at rest, unless another force is acted upon it. Newton’s second law of motion is about the formula for force, which is force= mass*acceleration. Newton’s third law of motion is for every action there is an equal and opposite reaction. Furthermore, Isaac Newton created the three laws of motion.
This reflective essay will demonstrate the concept of reflection. The model of reflection by Driscoll, 2007 has been followed in this essay to reflect the clinical skills that I have studied and practiced in week 7to week 9 of this unit which assisted me to get prepared for the practical experience which I will commence at the end of this semester. I have practiced numerous skills during the practicals class, but this essay will be a focus on taking care of bedsore and wound management.
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
My sixteen week class in English 111. I was really nervous about this class. Because English has never been my strong point. This class has hard, but fun all at the same time. I learn a lot from this class. Meanwhile,the first day of class you handed a paper with a question on it. “The first thing I want to say to you who are students is that you must not think of being here to receive an education; instead, you will do much better to think of being here to claim one.” Even though putting my all in what I have learned, claiming my education with hard work because using the skills of the meal plan, as we write to different audiences and learning to be a Critically thinker as I start becoming a critically-Literate Citizenship.
Isaac Newton and Aristotle both conjectured how motion of bodies work by offering their own explanations. Aristotle wanted to answer the question of why a ball tossed into the air will seemingly always stop at some point, so he conjectured that it is a natural tendency (i.e. a general law) for all objects to want to come to rest (Smoot). As Newton comes along, he suggests that objects will always travel in a straight line at a constant velocity, and that the existence of friction (or some other outside force) is what causes objects to stop at some point. While these statements may seem contradictory, as the Bohr Model and more recent models may also seem contradictory, it is natural to assume that at least one of these statements must be false. However, making such a claim again ignores the physical context in which the phenomenon resides. Aristotle’s conjecture is true, as long as the ball is always thrown on Earth where there is an atmosphere. Therefore, it can be seen that the truth of a general law is dependent on what one means by the word always. Newton’s laws may be more true on a broader level, but even they fail when an object is moving near the speed of light. Hence, Newtonian mechanics is only true if one assumes that the

“A body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force (Inertia, paragraph 1).” Suppose a car, going 50 M.P.H., hits a pole. The driver would be ejected out of the windshield, due to his body wanting to stay in motion. If that same car were to take a turn too quickly and lose traction, it would continue in the same direction it was going. Before hitting a pole, suppose this same guy set a mug of coffee on the top of his car, while he put air in his tires at the air pump. He then got in his car and drove away, forgetting about the mug. When he finally realized he forgot it, he pulled over to get it, but it was gone. He went back to the air pump to find his shattered mug on the ground. The man later decides to go bowling, so he put a bowling ball in the hatch of his car. He peels out because he is late and suddenly hears a shatter. The man pulls over and sees a bowling ball sized hole in the back windshield. What a smart idea!
This law is also often called “Inertia”. Inis the tendency for an object to resist the change in motion. Like, if you are moving and nothing happens to you, then you will keep moving. Forever. If nothing is happening to, and nothing is trying to put any type of force on you then nothing will happen .Forever. (Newton’s Three) There is a limit that must be met in order for the first law to be suitable to any given motion. The limit is represented by the phrase "... unless acted upon by an unbalanced force." As the long as the forces are balanced - the first law of motion
Bottle rockets are great models to examine Newton’s three laws of motion. The bottle rocket will remain on the ground until an unbalanced force, water, thrusts the rocket upward. This is defined by Newton’s first law of motion: an object at rest stays at rest or an object in motion, stays in motion (in the same direction/at the same speed) unless acted upon by an unbalanced force. It is also known as the law of inertia.
The object was created by Sir Isaac Newton to demonstrate conservation of momentum of energy through five swinging spheres. When one end of the device is lifted and then released it strikes the other spheres and the direct force causes them to move. The first ball might have caused the impact but it was not capable of moving itself and another sphere did not move it. The force that created the initial reaction was outside of the Newton’s cradle. Newton however had a very different outlook on motion “The Newtonian motion which remained, however, is the result of conflict, lacks any purpose or goal and has nothing to do with the divine life itself. Aristotle, and indeed Plato before him, would have viewed such motion” (SIMON OLIVER) Even though both famous academic thinkers came to the same conclusion that everything in motion must have be placed in motion they cannot come to the same conclusion “Ultimately, all motion is seen as a participation in the most perfect "motionless motion" of the Trinitarian Godhead in which all things are known, and thereby created and sustained, in the eternal emanation of the Son from the Father. By contrast, Newton outlined a view of motion which saw this category as a primitive state to which bodies are indifferent. Thus motion tells us nothing about the ontology of creation.
The second law is, “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” The heavier object requires more force to move an object, the same distance as light object. The equation gives us an exact relationship between Force, mass, and acceleration.
