Dane is holding an 8 kilogram box 2 metres above the ground. how much energy is in the box's gravitational potential energy store? assume dane is on earth, where g = 10 n/kg.

156.8 Joules of energy is in the box's gravitational potential energy store

Explanation:

Given:

Mass of the box Dane is holding = 8 Kilograms

Height at which Dane is holding the box above the ground= 2 metres

To Find:

Gravitational potential energy in the box=?

Solution:

gravitational potential energy is the work done per mass on a object to move that object from one fixed location to to another location against gravity.Its unit is joules or J

Thus  Gravitational potential energy is  represented as,

where

is the gravitational potential energy

m is the mass

h is the height

g is the gravitational force( 9.8 )

Now substituting the given values,

their crystal patterns have been disrupted by stress

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
