Show hintHide hint
Remember the variables associated with height and mass.
3Question 3.
What is potential energy?
- Stored energy
- Kinetic energy
- Thermal energy
Show hintHide hint
Think about energy that remains until acted on.
4Question 4.
Is gravitational potential energy dependent on the path taken?
- True
- False

Recall the definition of conservative forces.
Question 5.
A roller coaster car has a mass of 500 kg. If it reaches the top of a hill that's 30 m high, calculate the gravitational potential energy at that height. What will its kinetic energy be when it descends to ground level?
Show hintHide hint
Use gravitational potential energy formulas.
Question 6.
A spring with a spring constant of 1000 N/m is compressed by 0.1 m. Calculate the potential energy stored in the spring and the energy if it were to be released.
