Instantaneous speed is the actual speed at the present time, and average speed is the total distance divided by the total time. It measures the actual speed of the car at the time. Instantaneous speed:- It is the rate of change of position with respect to time,at that instant.

Average speed:-Average speed is defined as the total path length travelled divided by the total time interval. There are multiple differences between a mountain bike and a ten speed.

Mountain bikes are often lighter bikes than the average ten speed. Also speed has distance n velocity has displacement. Droop mode is when the governor of the prime mover is not controlling the frequency or speed of the generator.

The energy is controlled based on the difference between the speed setpoint and the actual speed. Average speed is a value of all the speeds you have travelled at over a certain length of time. Top speed is the absolute highest or fastest speed that you have ever reached.

A one time speed value. Average speed allows you to change the instantaneous speed throughout the travel time, while during constant speed, one keeps there instantaneous speed at the same numberAverage speed is when a car is moving with a speed of 25 miles per hour.

Constant speed is speed maintained consistency over time. Avg velocity is the speed you are going. Constant acceleration is the rate you increase your speed. That's correct, the instantaneous magnitudes are equal. Non-instantaneous values may not be equal. For example, to find average speed, between two points, you divide the actual path distance by the time, but for average velocity you divide the straight line distance, between the points, by the time.

The straight line distance could be quite a bit shorter then the actual path distance for curved motion so you could get a big difference between those averages. When calculating "instantaneous" values, however, the difference between "actual path distance" and "straight line distance" becomes insignificant, because you are using distances for infintesimally small time intervals. The difference is that constant speed doesn't change but variable speed does.

Suppose you accelerate in your car from stopped to 50 km. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km. Average speed is a measure of the distance traveled in a given period of time; it is sometimes referred to as the distance per time ratio.

Suppose that during your trip to school, you traveled a distance of 5 miles and the trip lasted 0. The average speed of your car could be determined as. On the average, your car was moving with a speed of 25 miles per hour. Solution : Actual speed gives instantaneous speed of a body at any instant but average speed is the total distance covered by total time taken.
