Instantaneous speed is the velocity of an object at a certain time. For example:- Suppose you are driving in a car and the speedometer constantly varies; this is because the speedometer gives speed at a particular moment of time.
When instantaneous speed does not change, an object is moving at. constant speed; in this situation average speed and instantaneous. speed are the same. Speed and direction of motion is velocity. Acceleration is the change in velocity divided by the time it takes for the. change to happen. It can be a change in speed or a change in direction or. both. Acceleration can be calculated using this formula: a = ( final speed - initial speed ) time.
