Learn and revise motion in a straight line, acceleration and motion graphs with BBC Bitesize Combined Science AQA Synergy study guide.

The velocity time graphs give all three variables for motion–velocity which can be read off at any time. Area is displacement and gradient is acceleration. Next page ...

The x 0 is the starting postion (at t = 0) and v 0 is the velocity at time zero. So, for this case, ... But if you calculate the acceleration without the graph, ...

Since the acceleration is defined as the change in velocity divided by the change in time, the slope of a velocity-time graph will be the acceleration of the car.

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

Instantaneous Velocity. Instantaneous velocity is defined as the limit of the average velocity as the time interval Δt becomes infinitesimally small. Its dimensions are [M 0 L 1 T-1] and its S.I ...
