Section 1: Forces and motion
a) Units
1.1 use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second2 (m/s2), newton (N), second (s), newton per kilogram (N/kg), kilogram metre/second (kg m/s).
Unit of mass=Kilogram (kg) Unit of distance=Metre (m) Unit of speed or velocity= Metre per second (m/s) Unit of acceleration= metre per second2 (m/s2) Unit of Force= Newton(N) Unit of Time= Second(s) Unit of gravitational acceleration= Newton per kilogram(N/kg) Unit of Momentum= kilogram metre per second (kg m/s)
b) Movement and Position
1.2 plot and interpret distance-time graphs Distance = The change of position of an object is called distance. The diagram shows an example:
Figure 1 shows an object changes its position from A to B. So the distance travelled by the object is AB. Displacement = The change of position of an object in a particular direction is called displacement.
