A 15 kg tv sots on a shelf at a height of 0.3 m. how much gravitational potential energy is added to the television when it is lifted to a shelf of height 1.0 m?

Gravitational potential energy can be described as m*g*h (mass times gravity times height).

Originally,

15kg * 9.8m/s^2 * 0.3 m = 44.1 kg*m^2/s^2 = 44.1 Joules.

After it is moved to a 1m shelf:

15kg * 9.8m/s * 1 = 147 kg*m^2/s^2 = 147 Joules.

To find how much energy was added, we subtract final energy from initial energy:

147 J - 44.1 J = 102.9 Joules.
