Question
An 2 kg apple is hanging in a tree, 10 m off the ground. What is the gravitational potential energy of the apple
Solution
The gravitational potential energy (PE) of an object can be calculated using the formula:
PE = mgh
where: m is the mass of the object, g is the acceleration due to gravity, and h is the height above the ground.
In this case:
m = 2 kg (the mass of the apple), g = 9.8 m/s² (the acceleration due to gravity on Earth), and h = 10 m (the height of the apple above the ground).
Substituting these values into the formula gives:
PE = 2 kg * 9.8 m/s² * 10 m = 196 Joules
So, the gravitational potential energy of the apple is 196 Joules.
