A Ball Is Lifted To Some Height And Then Dropped. Which Of The Following Decreases When The Ball Is Dropped?, A. Kinetic Energy, B. Elastic Potential
A Ball is lifted to some height and then dropped. Which of the following decreases when the ball is dropped?
A. Kinetic Energy
B. Elastic potential energy
C. Total Mechanical energy
D. Gravitational potential energy
Answer:
D. Gravitational potential energy
Explanation:
The total mechanical energy never change.
When the ball is lifted, it gains potential energy and loses kinetic energy. When the ball is dropped, it gains kinetic energy and loses potential energy. Since it is stated that the ball is dropped, meaning it does not depend on the objects shape but rather on its weight and height from the ground. This energy is called Gravitational Potential Energy.
