#P2.1a
describe how to measure distance and time in a range of scenarios
#P2.1b
describe how to measure distance and time and use these to calculate speed
from graphs
#P2.1c
make calculations using ratios and proportional reasoning to convert units and to compute rates
conversion from non-SI to SI units
#P2.1d
explain the vector–scalar distinction as it applies to displacement and distance, velocity and speed
#P2.1e
relate changes and differences in motion to appropriate distance-time, and velocity-time graphs; interpret lines and slopes
#P2.1f
interpret enclosed area in velocity-time graphs
#P2.1g
calculate average speed for non-uniform motion
#P2.1h
apply formulae relating distance, time and speed, for uniform motion, and for motion with uniform acceleration
