Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

The speed of a body gives us an idea of how slow or fast that body is moving. For example if a car is running slow, we say that its speed is low. And if a car is running fast, then we say that its ...
