The gravitational potential energy of an object is given by the formula:
where:-
is the gravitational potential energy,-
is the mass of the object,-
is the acceleration due to gravity (approximately
on Earth),-
is the height above the ground.For the 10 N coconut hanging 3 m above the ground:
For the 7.5 N coconut hanging 4 m above the ground:
The difference in their gravitational potential energies is:
So, the difference in their gravitational potential energies is
.
