Challenge Problems
Push your limits with challenges.
Question 1
Consider a particle moving through a conservative force field. If it starts at a height of 5 m with a potential energy of 100 J, what potential energy does it have at a height of 2 m?
💡 Hint: Calculate the difference in potential energy to find the answer.
Question 2
A block slides down a frictional ramp. If its initial height is 4 m and the work done against friction is 10 J, how much kinetic energy does it have at the bottom?
💡 Hint: Convert potential energy calculations to kinetic energy considering energy loss from friction.
