Question

Calculate the change in gravitational potential energy

when a 1.5Kg box falls from a 2m shelf. Take
g=10N/Kg.

Answer 1

30J

Step-by-step explanation:

Given parameters:

Mass of box = 1.5kg

Height = 2m

Acceleration due to gravity = 10N/kg

Unknown:

Change in gravitational potential energy = ?

Solution:

The change in gravitational potential energy is given as:

ΔGPE = mgh

m is the mass

g is the acceleration due to gravity

h is the height

ΔGPE = 1.5 x 10 x 2 = 30J
