When friction slows a sliding block___ A) the block's kinetic energy is transformed into internal energy

B) the block’s potential energy is transformed into internal energy

C) the block’s internal energy is transformed into kinetic energy

D) the block’s internal energy is transformed into potential energy

A

Explanation:

When friction slows a sliding block, the kinetic energy of the block is transformed into internal energy .

The frictional movement of two surfaces over one another leads to the conversion of some of their kinetic energies to another energy - heat or thermal energy. Hence, the temperatures of the objects are raised in the process.

Therefore, when a sliding block is slowed down due to friction, some of the kinetic energy of the block would be transformed into internal energy in the form of heat.

The correct option is A.

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains
