Potential energy is often wrongly defined as the energy at rest. The correct definition of Potential Energy is that it is the energy possessed by an object due to its position or configuration.
Based on the word itself, objects that have potential energy must have the potential to do some work. A hanging flower vase has potential energy because it can do work if it falls to the floor.
Thus, the formula for Potential Energy is PE = mgh where PE stands for Potential Energy, m for mass, g for the acceleration due to gravity and h for the height of the object from the ground.
Solve this problem using the potential energy formula.
Thus, these are the given in the problem:
Mass = 0.25 kg
Height = 10 m
Potential Energy = unknown
PE = mgh
PE = (0.25 kg) (9.8 m/s2) (10 m)
PE = 24.5 J
The potential energy of the Marang fruit is 24.5 Joules.
A 30 kg boulder is on top of an 80 m cliff. If the rock falls, how much is its potential energy when it reaches 30 m above the ground?
