Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -The greater ‘mass’ a moving object has, the more kinetic energy it has. A rock at the edge of a cliff has ‘kinetic’ energy because of its position. Friction causes some mechanical energy to change to ‘thermal’ energy. Energy that is stored is ‘kinetic’ energy.

Detailed explanation-2: -Once the rock falls, the potential energy is transformed into kinetic energy. The more potential energy, the more kinetic energy. In this case, the bigger the rock, or the taller the cliff, the more kinetic energy!

Detailed explanation-3: -The type of the energy of the rock at the edge cliff is potential energy.

Detailed explanation-4: -Energy is measured in Joules (J). Energy in the form of motion is kinetic energy. A rock at the edge of a cliff has gravitational potential energy because of its position. Energy that is stored is potential energy.
