What is a scalar quantity?

A quantity with magnitude only, no direction.
e.g. distance, speed

Of distance, displacement, speed and velocity, which are scalars and which are vectors?

Scalars: distance and speed. Vectors: displacement and velocity.

True or false? Acceleration is a scalar quantity.

False. Acceleration has a direction, so it is a vector.
