What's on this checklist
Core
- I can describe how rulers are used to find a length and how measuring cylinders are used to find a volume.
- I can describe how clocks and digital timers are used to measure a range of different time intervals.
- I can find an average value for a small distance, and for a short time interval, by measuring multiples of it, for example timing several periods of oscillation of a pendulum.
Extended
- I understand that a scalar quantity has only magnitude (size), while a vector quantity has both magnitude and direction.
- I know that distance, speed, time, mass, energy and temperature are scalar quantities.
- I know that force, weight, velocity, acceleration, momentum, electric field strength and gravitational field strength are vector quantities.
- I can find the resultant of two vectors at right angles to each other, by calculation or by a scale drawing, for forces or velocities only.
