Question

Define potential Energy. Write expression for Potential Energy possessed by a body lifted to

certain height ‘h’. A person of 60kg climbs a stair case and reaches to a height of 4m.

Calculate the potential energy acquired by the person. (take g = 10m/s2)​

Answer 1

Answer:

Potential energy is the work done to take a body to a certain height. For a body with mass m, h is the distance to which it is raised and g is the gravitational force acting on the body, then work done W is given as: W = force * displacement. W = mg * h.

Answer 2

Explanation:

The energy possessed by a body due to its position or shape is called potential energy.

P. E. = m * g* h

given- m = 60 kg

h = 4m

g = 10 m/s2

P.E. = 60 * 4 * 10

= 2400 joules ( J )
