Answer 1

When a baseball is at rest and then is thrown, what is the relationship between the ball’s potential and kinetic energy?(1 point)
Responses

As the ball’s potential energy decreases, its kinetic energy decreases.
As the ball’s potential energy decreases, its kinetic energy decreases.

As the ball’s potential energy increases, its kinetic energy decreases.
As the ball’s potential energy increases, its kinetic energy decreases.

As the ball’s potential energy increases, its kinetic energy increases.
As the ball’s potential energy increases, its kinetic energy increases.

As the ball’s potential energy decreases, its kinetic energy increases.

Answer 3

When a baseball is at rest, it has zero kinetic energy and maximum potential energy. As it is thrown and starts moving, its potential energy decreases while its kinetic energy increases. The total energy remains constant, but the distribution between potential and kinetic energy changes.

Answer 4

As the ball's potential energy decreases, its kinetic energy increases.
