# Physics questions/lab report | Physics homework help I have a lab report that requires some materials and photos. I have attached a word document listing the required materials and I will need photos of the procedures being done.

1. Define the term impulse.

1. Using the principle of momentum conservation, explain what happens when a moving billiard ball collides with a stationary ball (cue ball hitting the eight ball).

1. Explain the difference between energy and power and how they are related to work. Give examples of each.

1. A 1000 kilogram car is lifted 1 meter.

1. What is the potential energy with respect to the floor?

2. If the car is lifted 2 meters high, what is the new value of potential energy with respect to the floor?

3. Explain the following: Potential energy of an object varies linearly with position (height).

1. As you catch a fast-moving fastball, why is it wise to move your hand in the direction of the ball’s motion? Explain in terms of work and energy.

1. If a sprinter running at a speed of 10 meters per second could convert his/her kinetic energy into upward motion, how high could he/she jump?

1. What various forms of energy are present as you shoot a bow and arrow?
