Kelly is sledding on a snowy hill in the winter. The energy the sled has as it slides down the hill is a form of

A.

chemical energy.

B.

mechanical energy.

C.

potential energy.

D.

electrical energy.

B.

Explanation:

In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. Objects have mechanical energy if they are in motion and/or if they are at some position relative to a zero potential energy position, like if an object is vertical and in motion, much like the sled. Since the sled is in motion and going down vertically, the energy that it has as it's sliding down would be mechanical.
