Which is an example of kinetic energy

[From: ] [author: ] [Date: 11-11-07] [Hit: ]
D.-A-lol cheating much?......
A) an object held at a height.
B) an extended spring.
C) chemical energy in food.
D) movement of electrons in a conductor.
E) energy associated with charged particles.

D) movement of electrons in a conductor.
or NONE OF THE ABOVE

Kinetic energy is the energy of motion, and D) is the only type of energy that involves motion. However, movement of electrons is not normally considered kinetic energy; kinetic energy is normally studied as it applies to the movement of objects with appreciable mass that can undergo collisions and have mechanical forces applied to them, etc. So a rock falling from a rooftop would be a better example of kinetic energy.

The energy described by the others is as follows:
A) gravitational potential energy
B) elastic potential energy that has been expended (somewhere, there would now be an object with kinetic energy)
C) chemical potential energy
E) electrical potential energy

Kinetic- meaning moving. D.

-
A
