Linear Motion Graphs (2)

Example of velocity-time graph

The gradient of OA and the velocity and acceleration of the motorcycle

- The gradient of OA is positive and uniform - The velocity of motorcycle increases uniformly - Acceleration of motorcycle is uniform

The gradient of AB and the velocity and acceleration of the motorcycle

- The gradient of AB is zero - The velocity of motorcycle is constant - The acceleration of motorcycle is zero

The gradient of BC and the velocity and acceleration of the motorcycle

- The gradient of BC is negative and zero - The velocity of the motorcycle decreases uniformly - The motorcycle is moving with negative acceleration or uniform deceleration

The gradient of CD and the velocity and acceleration of the motorcycle

- The gradient of CD is zero - The velocity of motorcycle is zero (motorcycle is stationary) - The acceleration of motorcycle is zero
