Which one of the following is a scalar quantity?
- AForce
- BPressure
- CVelocity
- DAcceleration
- ENone of the above / More than one of the above
Show answer and explanation

A scalar quantity has only magnitude and no direction.
Pressure acts equally in all directions, so it is a scalar.
Force, velocity and acceleration have both magnitude and direction, making them vector quantities.
