Question

What is the potential energy of a bird sitting in a tree if the bird has a mass of 2Kg and it is 10 meters above the ground?

Answer 1

The potential energy of a bird : 196 J

Further explanation

Given

mass of bird = m = 2 kg

height = h = 10 m

Required

The potential energy

Solution

Potential energy is the energy that objects have because of their position. Usually related to the earth's gravitational force

Can be formulated

PE = m g h

g = acceleration due to gravity ⇒ 9.8 m/s²

Input the value :

PE = 2 kg x 9.8 m/s² x 10 m

PE = 196 J
