Find the pottential energy of a boy of mass 10kg standing on a building floor 10 meters above the ground level p.e?
PE = F*h = mg*h = 98*10 = 980 Joules.
To find the potential energy (PE) of an object, you need to know its mass (m) and its height (h) relative to a reference point. In this case, the reference point is the ground level.
The formula to calculate potential energy is:
PE = m * g * h
Where:
PE is the potential energy
m is the mass of the object
g is the acceleration due to gravity (which is approximately 9.8 meters per second squared on Earth)
h is the height of the object above the reference point
Given:
m = 10 kg (mass of the boy)
h = 10 m (height of the building floor above the ground level)
Using the formula, we can calculate the potential energy:
PE = 10 kg * 9.8 m/s^2 * 10 m
PE = 980 Joules
Therefore, the potential energy of the boy standing on the building floor 10 meters above the ground level is 980 Joules.
