Question

A moving body need not have. (1)potential energy. (2)kinetic energy. (3)momentum. (4)velocity​

Answer 1

Answer:

2). Kinetic energy.

Explanation:

Kinetic energy is the correct ans

Answer 2

A moving body need not have 1) POTENTIAL ENERGY .

Lets explain in detail :

• Potential Energy is a type of mechanical energy possessed by an object by the virtue of its position with respect to a reference frame.

• We commonly talk about GRAVITATIONAL POTENTIAL ENERGY , where the reference frame is earth surface.

However, a moving body will always have :

1. VELOCITY (v)

2. MOMENTUM (m × v)

3. KINETIC ENERGY (½ × m × v²)

These above quantities are all associated with motion.

But Potential Energy might not be present in a moving object (if it stays on earth surface).
