Question

The sum of mechanical energy, for a free fall of a body, at any point is always

Answer 1

sum of energy is always the sum of potential and kinetic energy of that body at any instant

Answer 2

Answer:

The ‘mechanical energy’ of a body that is falling freely under the gravitational pull effect which will always remain constant.

Explanation:

• A given mechanical energy is not one energy but it is actually the sum of “potential energy and kinetic energy”.
• Since mechanical energy is sum of kinetic energy and mechanical energy acting together the value of the sum will remain same at any given point when the body in which this mechanical energy is calculated is under free fall.
