Physical quantities and measurement techniques — Supplement Learning Objectives
Summary
- 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
