• Because it has both magnitude and direction.

• Because it only has magnitude.

• Because it is always positive.

• Because it does not have direction.

Density is defined as:

• the mass per unit volume of a substance

• the amount of heat in a substance

• the speed at which an object moves

• the force acting on an object
