Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected, so the difference was fairly significant. This happened because of friction, when the two pucks collided, they have lost a bit of their momentum, so the momentum after the collision differed. Kinetic energy differed more than what was expected, it was significantly less after the collision, the difference before and after the collision was 63.7%, so 36.3% of that momentum was lost. This have occurred because the collision is inelastic and since there was friction when the two pucks collided, their speed became less, and speed is directly proportional to kinetic energy.

Category 2: the change of momentum before and after the collisions differed slightly, the change of momentum before the collision was less than that after the collision. This was not what was expected, but because the collision was inelastic and experienced friction when the two pucks collided, the time before the collision differed from that after the collision. After the collision, the pucks lost some speed and so it took more time to cover the same distance before the collisions. In the equation time will become less and change in momentum is directly proportional to time.

Category 3: the pucks did stick together when they collided and moved together. The total kinetic energy did differ significantly, the difference between the collision before and after was 77.3%, so 22.7% of the energy was lost after the collision. This occurred because it was an inelastic collision. Due to the colliding and sticking together, that rest of the energy lost, was transferred to thermal and sound energy. What has been expected about this category was true to conclude then.

Category 4: isolating and solving for the mass using the conservation of momentum formula seemed fairly workable. The mass that was calculated tended to be 0.152kg or 152g. this...

Abstract
The purpose of this experiment, was to prove the concept of the uniform linear motion by using an air track. With this, we demonstrated the impulse and change in momentum, the conservation of...

...Collisions in Two Dimensions
Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this, both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity, allowing for future finding of momentum and kinetic energy values. By finding these, it was possible to...

...CollisionLab Simulation
Purpose: To study elastic and inelastic collisions in one-dimension.
Background Information:
Momentum: is a measure of mass in motion. It is the product of mass x velocity.
Conservation of Momentum: in the absence of external forces, such as friction, the linear momentum of a system remains constant.
Procedure:
1. Open web browser and go to the site: http://phet.colorado.edu
2. Click “play with sims”, then...

...Simple 1D Collisions PhET Lab
Introduction: When objects move, they have momentum. Momentum, p, is simply the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum, p, is kgm/s. During a collision, an object’s momentum can be transferred to impulse, which is the product of force (N) and time (s) over which the force acts. This allows us to write the momentum-impulse theorem:
Procedure: Play with the Sims ...

...1) Introduction
This Lab is about conservation of momentum. It is to investigate the difference of momentum before and after collisions. Using the photo gates record the velocity of each cart, comparing momentum and kinetic energy to find the law. The experimental apparatus are two red carts in approximately same weight and a gold cart in lower weight than the red ones, a stable air track (blow a constant stream of air out through numerous tiny holes) with low...

...height increases the energy stored in the ball and so when dropped, more of the energy would be converted to kinetic energy as a result of which the velocity at which the ball would strike the crater would be more and increasing the impact force of collision resulting in a deeper crater.
* Variables-
* Dependent- The depth of the crater.
* Independent- The height at which the ball is dropped from.
* Control-
* Mass of ball
* Type...

...isolated system, if no net external force acts on a system of particles, the total linear momentum of the system cannot change. There are two simple types of collisions, elastic and inelastic. If the total kinetic energy of the two systems is conserved then the collision is known as elastic. If the kinetic energy is not conserved, then the collision is inelastic.
