Understand that a scalar quantity has magnitude (size) only and that a vector quantity has magnitude and direction.

Know that the following quantities are scalars: distance, speed, time, mass, energy and temperature.

Know that the following quantities are vectors: force, weight, velocity, acceleration, momentum, electric field strength and gravitational field strength.

Determine, by calculation or graphically, the resultant of two vectors at right angles, limited to forces or velocities only.
