Velocity-time graphs show how the velocity (or speed) of a moving object changes ... is accelerating at an increasing rate – non-uniform acceleration. A line upwards curving to become flat ...

If we draw distance time graph for uniform motion then it will be straight line. For better understanding we can take an example, a car is running at a constant speed say 20 metres per second ...

How to measure acceleration of an object: measure instantaneous speed of object at two points (point A and point B) on route measure time for object to travel between point A and point B find ...
