1.5 know and use the relationship between acceleration, velocity and time
Acceleration is the rate at which objects change their velocity. The rate of decease of velocity is called deceleration. It is just a negative acceleration. It is defined as follows:
acceleration = (final velocity – initial velocity)/ time taken
1.6 plot and interpret velocity-time graphs
Velocity-time graphs represent the acceleration of any object. Velocity(m/s) is in the Y-axis while Time is the X-axis.
Some common velocity-time graphs:
