Answer 3

What do you think keeps the pendulum mooooooooving ??

Answer 4

Yea..you can say it keeps moving because of conservation of energy..
But the potential is due to the gravitational field.

Mechanical energy is simply a term to denote the summation of PE and KE.

Hence the answer should be Gravitational Energy.
@agent0smith Am I correct ??

Answer 5

Kinetic energy is linked to potential energy. As the ball moves from higher potential to lower potential; its kinetic energy increases, and vice-versa.

Answer 6

Consider a ball to be released at 'rest' from a height 'h' above the ground.
Describe the motion.

Answer 7

Without gravitational potential energy, pendulums don't move

Answer 8

You're welcome :)
