Question

A 2.4kg toy falls from 2m to i1m. What
is the change in GPE?​

Answer 1

Answer:

24 J

Explanation:

Change in height h = 2 m - 1 m = 1 m

Change in GPE

= mgh

= 2.4 kg × 10 N/kg × 1 m

= 24 N × 1 m

= 24 N m

= 24 J

Answer 2

The change in gravitational potential energy is 24 joule.

Given:

A 2.4kg toy falls from 2m to 1m.

To Find:

The change in gravitational potential energy.

Solution:

To find the change in gravitational potential energy, we will follow the following steps:

As we know,

Potential energy is dependent on height and gravitational potential energy is energy due to the gravitational force of the earth.

So,

Change in GPE = mg(h2-h1)

Here,

m is the mass of the body and h2,h1 is the height.

h2 = 2m

h1 = 1m

Acceleration due to gravity(g) = 10m/s²

Now,

In putting values we get,

$GPE = 2.4 \times 10 \times (2 - 1) = 24 \: joule$

Henceforth, the change in gravitational potential energy is 24 joule.
