1.1 — Physical quantities and measurement techniques

Core

  • 1.1.1 — Describe the use of rulers and measuring cylinders to find a length or a volume
  • 1.1.2 — Describe how to measure a variety of time intervals using clocks and digital timers
  • 1.1.3 — Determine an average value for a small distance and for a short interval of time by measuring multiples (including the period of oscillation of a pendulum)

Supplement

  • 1.1.4 — Understand that a scalar quantity has magnitude (size) only and that a vector quantity has magnitude and direction
  • 1.1.5 — Know that the following quantities are scalars: distance, speed, time, mass, energy and temperature
  • 1.1.6 — Know that the following quantities are vectors: force, weight, velocity, acceleration, momentum, electric field strength and gravitational field strength
  • 1.1.7 — Determine, by calculation or graphically, the resultant of two vectors at right angles, limited to forces or velocities only
