Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It is the amount that velocity changes per unit time. The change in velocity can be calculated using the ...

Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

The first equation can be derived using a velocity-time graph for a moving object with an initial velocity of u, final velocity of v and acceleration of a. The velocity of the body changes from A ...

Displacement/Time taken = 200 m towards East/ 100s = 2m/s towards East In this case the magnitude or size of speed and velocity of the boy is equal i.e. 2m/s. Note: The magnitude of speed and ...
