It shows how fast an object is moved. Instantaneous speed is the motion rate of object at a particular time period or moment. If we take an example of a cheetah who is running with speed of 80 miles per hour then it is his instantaneous speed because it is shown as in per hour speed.
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.
