Question

A body of mass 1 kg falls from a height of 5 metre how much energy does it possess at any instant. Take gravity= 9.8m per second square.

​

Answer 1

Answer:

49 joule

Explanation:

What is potential energy?

Potential energy is the energy that is stored within a body or the energy possessed by the body by virtue of its position.

Now come to the question

Given :–

Mass of the body(m) = 1 kg

Height(h) = 5 m

Acceleration due to gravity(g) = 9.8 m/sec²

Let:-

Potential energy be P. E, then the formula is mgh

P.E = mgh

P.E = 1 x 9.8 x 5

P.E = 49 Joule

Therefore:-

It possess 49 joule of energy at any instant.

Answer 2

Answer:

Mass of the body(m) = 1 kg

Height(h) = 5 m

Acceleration due to gravity(g) = 9.8 m/sec²

Now,

Potential energy be P. E, then the formula is mgh

P.E = mgh

P.E = 1 x 9.8 x 5

P.E = 49 Joule

Hence, it possess 49 J of energy at any instant
