The units you must know for this topic are as follows:
Mass: kilogram (kg)
Displacement: metre (m)
Velocity: metre/second (m/s)
Acceleration: metre/second/second (m/s^2) and newton/kilogram (N/kg)
Force: newton (N)
Time: second (s)
Movement and Position
Distance-time graphs
Velocity-time graphs
SUVAT equations
Distance/Time = Speed, as Speed is the distance travelled per unit time. We always use the standard units of metres (m) for distance, and seconds (s) for time unless specified.
When you plot a graph of distance against time, distance is on the y-axis and time is on the x-axis.
Using this information, can you figure out what the gradient at a point of this graph would represent?
