Scalars & Vectors Flashcards

All 6 cards in this deck

What is a scalar quantity?

A quantity that has magnitude (size) but no specific direction.

What is a vector quantity?

A quantity that has both magnitude (size) and a specific direction.

Name four vector quantities from the Physics specification.

Displacement, velocity, acceleration, force, weight, momentum (any four).

Name four scalar quantities from the Physics specification.

Distance, speed, mass, energy (any four).

True or false? Force is a scalar quantity.

False. Force is a vector — it has a size and a direction.

True or false? Mass is a scalar but weight is a vector.

True. Weight is a force acting downwards, so it has direction; mass has size only.
