Question

Mechanical energy often changes between potential and kinetic energy. True or False

Answer 1

I wanna say its ture but it didnt exactly say that is transfered from those types of energy so I would just say false

Answer 2

It is true that the Mechanical energy is often changes between potential and Kinetic energy.

Explanation:

Mechanical energy is the aggregate of potential energy and kinetic energy of an object. When the object is ''stationary'' or at ''rest'', potential energy will be maximum and kinetic energy will be zero.

When the object starts to move, potential energy decreases and kinetic energy increases from zero. As the distance moved by the object increases, potential energy reduces gradually.
