Challenge Problems
Push your limits with challenges.
Question 1
A particle moves under the influence of a central force. If the radius of motion doubles, how does it affect the potential energy?
💡 Hint: Consider how potential energy varies with radius.
Question 2
Calculate the work done by a non-conservative force over a distance if the path taken is different, and energy is lost due to friction.
💡 Hint: Use the force of friction and distance to find work done against movement.
