The Matchbox Momentum lab helped us learn about the rules of momentum. Momentum is basically defined as mass times velocity, which is the weight of something multiply by how far something goes in a set time with a direction. When working through the lab there were “rules” or concepts you picked up when working through it. For example, when velocity increases momentum increases. Also, when mass increases momentum increases. In the lab, when looking at the double marble and double textbook trial and the single marble and double textbook trial you can see that the momentum is doubled when the mass was doubled. A piece of evidence, that shows when velocity increases mass increases, is when you look at the single marble and double textbook trial
The linear momentum of a particle of mass, m, moving with a velocity, v, is defined to be the product of the mass and velocity: p=mv
On a constant basis, we experience Newton’s Laws of Motion, but do not know it. In 1687, Sir Isaac Newton formally published his three immortal Laws of Motion into one of his greatest works. The third and shortest of these scientific marvels, relating to momentum, states that every action force has an equal and opposite reaction force, which is true in both science and life, although we can barely detect certain hypothetical reaction forces. An exemplary instance of this is when parents educate their children, then children then educate their parents in return, a barely detected “reaction”. The power of children are also shown in classic literature, especially the works of The Bard, William Shakespeare. The jinxed “Scottish Play”, Macbeth,
...ys that for every action there is an equal and opposite reaction, and this is also displayed when a bat hits a ball. The bat exerts force on the ball, just as the ball exerts force on the bat. This force can sometimes even be enough to break the bat, like in the illustration below.
Newton's cradle is a series of five balls hung on thin string. One (or 2) ball(s) is pulled back and the energy travels through the balls and the one (or 2) depending on how many were pulled back go up.
Physics is everywhere. Consequently, physics is a part of sports and more specifically, hockey. As the scientific discoveries progressed with time, so did the advancements in the sport of hockey, reflecting on how important and influential science truly is. Physics takes part in the ice, the skates, the protective gear, the shots, goaltending, and all other aspects of ice hockey.
The definition of physics by some may be the science that deals with matter, energy, motion, and force. Therefore everything in the world uses physics in some way or another. One of the numerous things that deal with physics is bowling. Some of the major parts of physics bowling has is the motions, the ways that Newton’s laws apply, the different momentums, and the energy. Other physics topics include torque, pendulum theory and collisions.
The number and strength of collisions is increased so that the reaction can happen faster than it should. If the particles have more energy then more particles will be able to react to it. Solid reactants like marble chips are affected by surface area. The larger the surface area, the more collisions that will take place.
The force and impact of collisions have truly been based off the material that cars have been built with. In the past, cars were built with heavy parts and steel as it was believed to be a safe way to protect occupants in the car as the structure would be more solid. Although, this is not the case since with a heavier and stronger body, the time of the collision would be very minimal which would overall increase the force of the impact based on the car’s specific velocity and mass. On the other hand, modern cars utilise a specific feature called a Crumple Zone. The Crumple Zone is implemented in cars through the way they have been shaped with the metal. The metal in the outside of cars have been heated, cooled, and molded in a way to be able
When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?
We ran into Newtons First Law, which claims that an object resists change in motion, as the marble rolled down the floor it didn’t stop until it was acted against by friction. As we moved on, Newtons Second Law came into play when we were creating our lever as we need a ball that would roll down with enough acceleration that it could knock down the objects. Newton’s second law claims, that F=MA. So, we choose a golf ball since it would have more mass than a rubber ball, but it would have less acceleration when the lever was started. This way, it would knock the upcoming objects. Newtons Third Law claims that every action yields an equal and opposite reaction. This is proven in our Rube Goldberg Machine when the small car was rolling down the tracks as the wheels pushes against the track making the track move backwards. The track provides an equal and opposite direction by pushing the wheels forward.
The surface of the marble affects the amount of friction, which affects the speed and distance the ball rolls. The surface of the floor also affects the amount of friction, which affects the speed and distance the ball rolls.
Newton’s three laws of motion state that: 1. an object’s state of motion tends to remain constant, unless an external force is applied. 2. The force applied to the object is equal to the mass of the object multiplied by its acceleration, and the force and acceleration vectors are in the same direction 3. For every action, there is an equal and opposite reaction. When considering these laws in the analysis of a hard collision in football, we make a few observations.
Before I explain and talk about why a ball goes farther when hit with an aluminum bat, I would like to present and explain some vocabulary concept and words. A collision, transfers momentum or kinetic energy from one object to another object. There are two types of collisions, elastic collision and inelastic collision. An elastic collision is a collision that occurs when two objects bounce apart when they collide; the total kinetic energy in the system is the same before and after the collision. For example, elastic collision occurs when equally massive balls move in the same direction; in this case momentum is transferred from one ball to another ball. And an inelastic collision is a collision that occurs when two objects collide and do not bounce away from each other; the collision changes the total kinetic energy in a closed system. For example, inelastic collision occurs when two cars crash and join themselves into one; the objects stick together after colliding. In inelastic collision all that happened is the loss of some kinetic energy, objects don not necessarily need to stick together in an inelastic collision. Whether a collision is an elastic collision or inelastic collision momentum would always be the same before and/or after the collision as long as you have a close system.
We did not have a specific place on the ramp at where we would drop the mass pieces onto the trolley. We just dropped them anywhere on the ramp. The position of the collisions was different for all three trials which might have affected the results because the distance after the collisions was different for every collision. There was no consistency.
In this lab, we were looking at the conservation of matter, chemical reactions and using mass to find the number of moles present after a reaction. We had previously studied moles (measurement system) and mass. We copiously took notes on the masses of the objects after reactions and observed how the quantity would “change” after a chemical reaction. The conservation of mass is a law that states a mass will stay consistent over time and will not change until it is not combined or removed. We performed a lot of chemical reactions in this lab. The first part of the lab was putting a coiled piece of copper in silver nitrate and washing it out with water. The second and third part was also about adding chemicals and seeing the reactions. The purpose of the experiment was to determine if the values of silver and silver nitrate would stay the same. The hypothesis was that if chemical elements and compounds react the ratio would stay the same, due to the conservation of mass and the law it has.
