An object that is stationary has what energy?
When a baseball is at rest and then is thrown, the relationship between the ball's potential and kinetic energy is as follows:
Initially, when the ball is at rest, it has no kinetic energy but possesses potential energy due to its position relative to the ground. This potential energy is known as gravitational potential energy.
As the ball is thrown and starts to move, its potential energy decreases while its kinetic energy increases. The ball's potential energy is being converted into kinetic energy as it gains speed and motion.
At the highest point of the ball's trajectory, its potential energy reaches its minimum value (almost zero) while the kinetic energy is at its maximum.
As the ball continues to fall towards the ground, its potential energy remains relatively low, while its kinetic energy increases even more.
When the ball reaches the ground, its potential energy is minimal (close to zero), and the kinetic energy is at its highest, representing its maximum speed.
Therefore, as the ball is thrown and moves, there is a transformation of energy from potential energy to kinetic energy.
