Kinematics
Definitions
Distance = the total length of the path travelled by an object
Displacement = the vector quantity indicating the straight line distance from the start point
of an object to its end point
Speed = the scalar quantity indicating the rate of change of distance travelled
Velocity = the rate of change of displacement
Acceleration = the rate of change of velocity
Graphs
Displacement-time graphs:
o Gradient is velocity
Velocity-time graphs:
o Area under is displacement
o Gradient is acceleration
SUVAT
