1.1Physical quantities and measurement techniques

1. Motion, forces and energy

Core

Describe the use of rulers and measuring cylinders to find a length or a volume.
Describe how to measure a variety of time intervals using clocks and digital timers.
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).

Extended

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.
