Calculate the change in gravitational potential energy
when a 1.5Kg box falls from a 2m shelf. Take
g=10N/Kg.

Sagot :

Answer:

30J

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
