Question 1.
What is the formula for calculating gravitational potential energy?
Show hintHide hint
Think about how mass, height, and gravity relate to energy.
Question 2.
If a 5 kg object is at a height of 3 m, what is its potential energy?
Show hintHide hint
Use the formula and plug in the values.
3Question 3.
What is gravitational potential energy dependent on?
- Mass
- Height
- Gravity
