Centuries of thought and experimentation by several of the greatest minds to ever walk the earth have contributed to the awareness of this property of matter known as Inertia. It all began with the investigation of an ancient Greek scientist and philosopher by the name of Aristotle. Through countless observations and hypotheses, Aristotle grew almost certain of a few things involving motion. Aristotle’s findings suggested mainly that Earthly objects seek their natural place at rest. This natural
Abstract Moment of Inertia is the measure of an object’s resistance to changes in the rotation direction. It is the rotational analog of mass for linear motion. The relationship of moment of inertia to angular acceleration is similar to that of the mass to linear acceleration. In the experiment, the scalar form or the mass of moment of inertia was used. The determination of the moment of inertia of a disk and a ring and to compare the moment of inertia of the solid disk rotated at two different
Exp # 1 Title: Inertia and Car accidents. Aim: To find out how inertia plays a part in accidents. Materials: 1. Wooden ramp, approx 1.5m long and 30cm wide. 2.

Measuring the Moment of Inertia of a Flywheel Objective ========= Measure the angular velocity of a flywheel and use conservation of energy to calculate its moment of inertia. Apparatus ========= Flywheel String Slotted mass on hanger Stop-watch Vernier caliper Metre ruler Theory ====== The rotational kinetic energy can be defined by the equation K=1/2 I ω2. Where I is the moment of inertia of the body about the axis of rotation. In this experiment
Objective: The objective of this laboratory was to theoretically calculate the moment of inertia of a disk and a ring and then to verify the moment of inertia for both objects through experiment. This laboratory shows that while the theoretical is not within the uncertainty of the experimental, both values are extremely similar to each other. Data and Analysis: Data: Table 1: The Angular Acceleration of No Ring and Ring Trial No Ring Ring 5g 4.57 ± 0.005 rad/s2 1.32 ± 0.005 rad/s2 10g 13.16 ± 0.005
modern definition of motion. These laws have now become known as the ‘Newton’s three laws’. The three laws of motion can be used to describe the relationship between a body and the forces acting upon it. The first newtons law, also known as the law of inertia explains why an objects motion cannot change unless, it is acted upon by an unbalanced force. It is commonly stated as ‘An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted
Born in 1564 - 1642, this scientist came up with a theory that led him to crate the law of inertia, this law contradicted Aristotle 's ideas of motion. He concluded that an object in the state of motion possesses inertia. Basically what he meant was that, "what is in motion stays in motion unless an object of equal or greater force acts upon it." Due to his vast studies of space, planets, stars and moons
upon by an unbalanced force.” Basically states what we know today as inertia. The law of inertia means that objects will try to keep on doing what they are doing presently. If a ball is rolling down a hill, Newton’s first law of inertia states that the ball will keep on trying to move down the hill. If the ball is resting on a flat surface it will not want to move anywhere, but instead it will stay stationary because the law of inertia states that it will stay there unless acted upon by an unbalanced
Physics of Soccer I. Introduction Soccer is a sport that’s very challenging and during the course of this semester I’ve found physics can also be described as challenging. As far as I was concerned soccer and physics were both challenging and that was all they had in common, consequently upon researching them both this semester I found that I was wrong. For me this was nothing new because I’ve found that physics isn’t a subject that can be skimmed, but rather it has to be studied to the finest
So why is it important to wear your seat belt? A driver or passenger travelling in a car is moving at the same speed as the car. If the car suddenly stops, the body of the rider inside will keep moving forward at the same speed. This demonstrates inertia. The tendency of a moving object to keep moving, or of a stationary object to remain at rest. Basically Newtons first law; that a body stationary or moving with constant velocity will want to continue to do so, unless acted on by a force. Lets understand
apply to every movement that is made on the field. To better understand the physics of a goalie, you must understand how Newton’s Three Laws of Motion work; Inertia, force equals mass times acceleration, and equal and opposite forces, as well as another law torque and leverage. The first law of Newton’s Laws is inertia. The basic definition of inertia is an object in motion will stay in motion until acted on by an outside force, as well as an object as rest will stay at rest until acted on by an outside
period does also. My reference Mark Nethercott says that if there are no outside influences, the period stays constant at about 15 degrees of arch, but the amplitude must be low. This statement corresponds with Newton’s first law of motion (law of inertia) that says, “Every object remains at rest or in motion in a straight line at constant speed unless acted on by an unbalanced force.” (Physics, A World View p.31). A force other than gravity and the length of the swing can alter the outcome of a
called “Newton’s first law of inertia”. Newton’s first law is commonly stated as “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted on by an outside force.” Put simply, an object that is moving will keep moving in the same direction and the same speed unless another force acts upon it and an object that isn’t moving won’t start moving unless there is another force that acts upon it. Inertia is the term that scientist use
Without these measurement and math the roller coaster can be the very dangerous since it could have too much potential energy and sends the cart out of the track. Two important factors of roller coaster beside the energy is Newton’s laws and gravity. Inertia define as “Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.” (Sir Isaac Newton). This law is basically how the roller coasters runs, the chains and the breaks on the roller
Swimming Techniques and Physics Presently scientist are conducting research to help people gain new techniques in swimming. While scientists continue research for new swimming techniques, they must start with early techniques of swimming as a sport and part of life. Learning how to swim is not easy. However, swimming is physics. There are laws, buoyancy, drags, and motions. To become a good swimmer one should take initiative to learn how certain techniques evolved and take an active approach
Newton came along in the mid 1600‘s. It is said he discovered this idea when he was hit in the head from an apple that fell from a tree. With this new idea, he tested and came up with the Three Laws of Motion. The laws are statements that explain Inertia, force and ...
There are many forces that play into an object falling down and hitting the ground. For a fragile object like an egg, making it survive a small fall is very difficult let alone four stories. It is possible to make the egg survive however, by encasing it in something. You can compare the egg to a human in a car. A car crash can be deadly however the car that is around acts like the objects you would encase an egg in. In a car crash, or in most collisions, there is a primary and a secondary impact
Ideas in the subject of Physics are never absolute; it is a forever-changing topic. We think we have discovered everything there is to know about it, and then we find out something new that changes everything. That is one of the reasons physics is so interesting to learn about – there will always be something new. There are many very important discoveries in Physics. This paper will describe some of the discoveries. These discoveries are prevalent throughout history and in our daily lives. One of

expressed in m/s2. Acceleration = Change in Velocity (m/s) (m/s2 ) Time taken (s) It is the property of matter that it opposes any change in an objectÂ’s fixed position. This is called Inertia. The greater the mass of an object the greater will be the force of Inertia. This indicates that to make an object move from its stationary position, it will take a
