Question

A ball with a mass of 500g is lifted onto a shelf which is 1.5m above the ground. Calculate the gravitational potential energy gained by the bal

Answer 1

First you would need to convert grams to kg:
500/1000=0.5

The equation for GPE is:
GPE[J]= m[Kg+metres] x g[N/kg+gravitational field strength] x h[m+height]

g or gravitational field strength is always 10 on earth.

So we know that:
m= 0.5kg
h=1.5m
g=10N/kg

So you would do:
0.5 x 1.5 x 10

Which is:
7.5

And since GPE is measured in joules the answer is 7.5J

Answer 2

The answer you asked would be

Step-by-step explanation:

Gravitational potential energy is the energy stored in an object due to its position above the Earth’s surface.

This is due to the force of gravity acting on an object. Gravitational potential energy is calculated as follows:

Ep = m × g × h so a Gravitational potential energy is the energy stored in an object due to its position above the Earth’s surface. so the answer would be A ball with a mass of 500g is lifted onto a shelf which is 1.5m above the ground. Calculate the gravitational potential energy gained by the ball (g = 9.8 N/kg).
