Force and potential energy: The only force acting on an object moving along the x-axis is the conservative force given by F(x) = (2.00 N/m)x + (1.00 N/m³)x³.
(a) What is the change in potential energy when the object moves from x = 1.00 m to x = 2.00 m?
(b) What is the change in kinetic energy when the object moves from x = 1.00 m to x = 2.00 m?
