Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction. Examples include temperature, mass, and time.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction. Examples include velocity, force, and displacement.

What do you need to fully describe a vector quantity?

Back

Both magnitude and direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to the speed of an object in a specific direction.
