Final answer:

The 0.200-kilogram ball at 1.00 meter from the ground is accelerating and experiencing an increase in kinetic energy as its potential energy converts to kinetic energy during its fall.

Step-by-step explanation:

When a 0.200-kilogram ball is 1.00 meter from the ground after falling from a higher point, it is experiencing an increase in kinetic energy because it is accelerating due to gravity. The ball is not at its highest point, nor is it experiencing an increase in potential energy; instead, the potential energy it had while on the shelf is being converted into kinetic energy as it falls.

Kinetic energy increases as the ball's velocity increases during its descent, up until the point of impact with the ground. The conservation of energy principle indicates that the potential energy lost is equal to the kinetic energy gained, minus any energy losses due to factors not considered in this ideal scenario, such as air resistance or friction if they were present.
