Question
Calculate the missing term. Take g as 10m/s2
m = 250kg, h = 10 m, GPE =? (Take g = 10 m/s2)
- 25KJ
- 250 J
- 2500 J
- 25000 J
Hint:
When the m is 250 Kg and h is 10 m, the GPE is 25 kJ.
The correct answer is: 25KJ
- Gravitational potential energy is calculated as GPE= mgh.
- m= 250 Kg, h= 10 m.
GPE= 250X 10X 10= 25000 J= 25kJ.

A roller coaster is at the top of a 72 m hill and weighs 966 N. What is its gravitational potential energy?
The energy that an object has or acquires when its position changes due to being in a gravitational field are known as gravitational potential energy. Gravitational potential energy can be defined as energy that has a connection to gravitational force or gravity.
Gravitational potential is the effort required to move a unit test mass from infinity into the source mass's gravitational field. Both are held above the table, with one at the table. We can now state that the pencil that is higher than the table will have more gravitational potential energy.
¶The formula for Gravitational Potential Energy
⇒ GPE = m⋅g⋅h
where
m represents the mass in kilograms.
Gravitational acceleration, or g (9.8 on Earth)
The measurement of h above the ground is in meters.
