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
