Question

How many joules of gravitational potential energy are stored in a system where a feather with a mass of 0.008 kilograms is positioned 22 meters above the ground? Can somebody help

Answer 1

G.P.E = 1.725 Joules

Explanation:

Given the following data;

Mass = 0.008 kg

Height, h = 22m

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

`G.P.E = mgh`

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

We know that acceleration due to gravity is equal to 9.8m/s²

Substituting into the formula, we have;

GPE = 0.008 * 9.8 * 22

GPE = 1.725 Joules
