Challenge Problems
Push your limits with advanced challenges
A 10 kg rock is lifted to a height of 20 m on a hill. Calculate its potential energy. Next, what would its potential energy be if raised to only 10 m?
💡 Hint: Use the formula and ensure to change the height value accordingly.
A car is lifted to a height of 1.5 m and weighs 1200 kg. Calculate its potential energy, and if it rolls down, what is the energy converted to kinetic energy?
💡 Hint: Remember, when kinetic energy is gained, potential energy is lost.
