Core concepts and learning points for this section:
Syllabus Points
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
