(a)
Interpretation:
Whether a sled resting at the top of a hill or a sled sliding down the hill has higher kinetic energy is to be determined.
Concept introduction:
Energy is defined as the capacity to do work. It is associated with both physical and chemical changes.
The two types of energy are as follows:
1. Potential energy: It is the energy due to the position of the object relative to the other objects.
2. Kinetic energy: It is the energy that arises due to the motion of the objects.
(b)
Interpretation:
Whether water above the dam or water falling over the dam has higher kinetic energy is to be determined.
Concept introduction:
Energy is defined as the capacity to do work. It is associated with both physical and chemical changes.
