A sphere is released into the atmosphere where air resistance is present. As it falls it loses 7J of potential energy. How much kinetic energy did it gain?

Respuesta :

Answer:

7 J

Explanation:

Given that,

A sphere is released into the atmosphere where air resistance is present.

The lose in energy is equal to 7 J

We need to find the gain in its kinetic energy.

We know that, as per the law of conservation of energy,

Loss in potential energy = gain in kinetic energy

⇒

Gain in kinetic energy = 7 J

Hence, the gain in kinetic energy is 7 J.
