describe how to measure distance and time in a range of scenarios
describe how to measure distance and time and use these to calculate speed
from graphs
make calculations using ratios and proportional reasoning to convert units and to compute rates
conversion from non-SI to SI units
explain the vector–scalar distinction as it applies to displacement and distance, velocity and speed
relate changes and differences in motion to appropriate distance-time, and velocity-time graphs; interpret lines and slopes
interpret enclosed area in velocity-time graphs
calculate average speed for non-uniform motion
apply formulae relating distance, time and speed, for uniform motion, and for motion with uniform acceleration
