Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best describes potential energy?
Energy of motion
Stored energy due to position or state
Energy released during a chemical reaction
Energy transferred as heat
2. What is the formula for kinetic energy?
PE = mgh
KE = 1/2mv²
W = Fd
P = W/t
3. Gravitational potential energy depends on an object's mass, gravity, and .
4. As an object falls, its potential energy is converted into energy.
5. A stretched spring stores potential energy.
6. Explain the difference between potential and kinetic energy, providing an example for each.
7. A 2 kg ball is held at a height of 5 meters. Calculate its gravitational potential energy (g = 9.8 m/s²).
8. If the same 2 kg ball is dropped and reaches a velocity of 7 m/s just before hitting the ground, calculate its kinetic energy.
9. An object at rest has zero kinetic energy.
True
False
10. The total mechanical energy of a system is always conserved, assuming no external forces like friction or air resistance.
True
False
