Kinetic energy:
1) A car traveling down the road has less kinetic energy than a semi-truck and traveling at the same speed because the car's mass is much less than the truck's.
2) A river flowing at a certain speed possesses kinetic energy because the water has a certain mass and it also has velocity.
3) An insect flying has a small amount of kinetic energy because its mass and velocity are relatively small.
Potential Energy:
1) The food we eat has chemical potential energy because as our body digests it, it provides us with energy for basic metabolism.
2) A stretched spring in a pinball machine has elastic potential energy and can move the steel ball when released.
3) When a crane swings a wrecking ball up to a certain height, it gains more potential energy and has the ability to crash through buildings.
the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person,
We know

Answer:
D
Explanation:
appearance is not a imp factor . location could be imp. becoz a proper environment is need to study such courses.
