Answer:
option B
Explanation:
The correct answer is option B
When the playground swing reaches the highest point the swing has high potential energy.
When the swing is at the bottom kinetic energy of the swing is maximum.
When the swing back down the potential energy at the top point of the swing is converted to the Kinetic energy.
so, U g --> K
Ug is the potential energy of the swing
K is the kinetic energy of the swing.
