Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

It covers topics such as position, displacement, distance, speed, velocity, acceleration, uniform and non-uniform motion, free fall, projectile motion, and graphical representation of motion.

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 ...
