Example 1:<br />
A 3.00kg box is lifted by an upward force 1.50m above the surface<br />
of earth to the top of a table. What is the potential energy of the<br />
box in its new position?<br />
Ep = mgh<br />
= 3.00kg x 9.81m/s2 x 1.50m<br />
= 44.1 J<br />
The gravitational potential energy of the box is<br />
now 44.1 J.
