Challenge Problems
Push your limits with challenges.
Question 1
If a ball is thrown into the air, how does the potential energy vary with height? Calculate the potential energy at various heights given m = 2 kg, g = 9.81 m/s².
💡 Hint: Remember to apply the formula PE = mgh for different heights.
Question 2
Given a non-conservative force (like friction) acting on a block sliding down an incline, describe how you would evaluate the work done against friction and its effect on mechanical energy.
💡 Hint: Think critically about energy transformations and how they affect overall energy conservation.
