The important thing is to never stop questioning. In science you must question everything and work to find the answer.The definition of the speed of something in a given direction. So when a car is moving north how fast it's moving would be its velocity. When the mass of an object is changed it can change the velocity. Mass is the amount an object weighs.In this experiment I took the mass of carts and changed them to observe their change in velocity.s. The law of conservation of momentum requires that the total momentum in the system must remain the same, or be conserved, even though mass or velocities of moving objects in a system may change. If the total mass of two colliding carts is increased, then the final velocity of the carts decrease?*…show more content…*

a) Click on the reset button. Adjust the glider masses back to 0.5 kg. Reposition the gliders with G1 on the left end of the track, and G2 on the right end, since both gliders will have an initial velocity moving toward each other for the collision. The exact position of each is not important, as long as they can collide near the middle. b) Record the masses of G1 and G2 in Table D. Calculate and record the combined mass of the gliders as well. c) Set the velocities to 3.0 m/s for G1, and –3.0 m/s for G2. Record the initial velocity and momentum of each glider in Table D as well. d) Press play to run the trial. After the collision, press pause to record velocity and momentum data for the combined gliders in Table D. e) Run a second trial. Click the reset button and change the mass of G2 to 0.8, and keep the other parameters the same. Record masses, velocities, and momentums as you did in Steps 3b–c, this time in Table E. Run the simulation, pausing after the collision to record postcollision velocity and momentum of the gliders in Table E. f) Repeat Step 3e to run a third trial where the mass of G2 is increased to 1.2 kg. Record masses, velocities, and momentum both before and after the collision in Table F.

Both carts can have the same mass and same velocity, but after the collision will have a slower velocity. Even after the collision the carts will have a velocity but their directions will have changed. When the carts change direction the velocities will change and the cart with the least amount of mass will have the greatest velocity. If one cart is moving faster in the beginning the one with the least amount of velocity will go backwards faster. Clearly, the velocity and mass of the cart affects the

## Kinetic Energy Lab Report

The purpose of the experiment was to use previous knowledge of velocity yo perform kinetic energy calculations, make calculations of gravitational potential energy, and to determine what affects GPE and KE more. What was determined to be true was that the potential energy was larger than the kinetic energy and that velocity had a greater effect on the kinetic energy because velocity doubles in the kinetic formula. At first the group had to convert the original ball’s mass from grams to kilograms by dividing by 1,000. Then the group had to determine the height of drop for each location and calculate the potential energy of each ball by doing
