Question

What is the gravitational potential energy of a 50kg object situated 8 meters above the Earth’s surface?

Answer 1

Answer:

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Answer 2

Given - Mass : 50 kg

Height : 8 metres

Find - Gravitational potential energy

Solution - To find the gravitational potential energy, formula used is U = m*g*h. In the formula, m represents mass, g represents acceleration due to gravity and h is representative of height.

Taking the acceleration due to gravity 10 m/s².

Keeping the values in formula, we get -

U = 50*10*8

Multiplying to get gravitational potential energy

U = 4000 Joules

Hence, 4000 joules is the gravitational potential energy.
