Describing quantities in physics

• A quantity that requires both a number describing its MAGNITUDE, and a Direction describing its path is known as a VECTOR.

For example:

1. Velocity
2. Acceleration
3. Force
4. Displacement

• A quantity that does not require direction to be fully described is known as a SCALAR.

For example:

1. Distance
2. Speed
3. Mass
4. Time
