Challenge Problems
Push your limits with challenges.
Question 1
Calculate the potential energy of a 12 kg object on a platform 15 meters high. Then, what would its potential energy be if it were lifted to 30 meters?
💡 Hint: Use the PE formula for both heights.
Question 2
If an object loses 500 Joules of gravitational potential energy when falling, calculate how high it was initially if its mass was 10 kg.
💡 Hint: Rearrange the PE formula to solve for height.
