Question

calculate the potential energy at a height of 7 m from the ground​

Answer 1

Let the mass be 'm'.

given,

height above the ground(h) = 7 m

acceleration due to gravity(g) = 9.8 m/s^2

to find: Potential energy

solution:

Potential energy is defined as the energy possessed by body by virtue of its position or configuration.

or, P.E = mgh

or, P.E = m * 9.8 * 7

or, P.E = (68.6*m) J

Therefore, Potential energy is (68.6*m) J

Answer 2

Given

• Height (h) = 7 m
• Acceleration due to gravity (g) = 9.8 m/s²
• mass (m) = m

To find

• Potential energy (P.E)

Solution

• P.E = mgh
• P.E = m × 9.8 × 7
• P.E = 68.6 m

Hence the potential energy of the body is 68.6m J
