Answer
Explanation:
Step1: Recall energy - conversion concept
When an object moves uphill, its height (h) relative to a reference - level increases. The gravitational potential energy is given by (U = mgh) (where (m) is mass, (g) is the acceleration due to gravity, and (h) is height), so potential energy increases.
Step2: Consider the conservation of mechanical energy
Assuming no non - conservative forces (like friction) act on the ball, the total mechanical energy (E=K + U) is conserved. As (U) increases, the kinetic energy (K=\frac{1}{2}mv^{2}) (where (m) is mass and (v) is velocity) must decrease to keep (E) constant.
Answer:
The ball is moving uphill, the kinetic energy is decreasing and the potential energy is increasing.
