How is average speed different from instantaneous speed

Both the above quantities are scalar and are measured with the help of a speedometer. Average Speed is a constant value and is measured by calculating the speed of an entire trip or journey. For a journey, it is not necessary that the body or an object remains at the average speed. Sometimes, it may have more value than the average speed or less value than the average speed depending on the path and hurdles.

Instantaneous speed is not constant for an object or a body. And it is measured with the help of the vehicle-installed speedometer. The speedometer tells the exact accurate value of the speed at that particular instant of time.

The value of the instantaneous speed is greater than or equal to zero. Also, instantaneous speed is a scalar quantity. It can be defined as the total distance traveled by the object or a body divided by the total elapsed time.

The formula for calculating the average speed is given below —. It can also be measured by calculating the speed of the entire journey or trip. It is believed that the average speed of an object or body is constant. Thus, the speed of the body is not usually constant, and distance traveled divided by time gives us the average speed of the object or body during that time.

It does not mean that the body is moving at the same speed throughout the journey. When the road is straight, flat, and free, the speed of the vehicle may be above the average speed, but on a curved road, hills, or in a crowded area, the speed may be slower than the average speed value. Instantaneous Speed can be defined as the speed of a body or an object at a particular instant in time. The formula for calculating instantaneous speed is given below —.

Instantaneous speed and average speed are both scalar quantities. When you solve the average of all instantaneous speeds that occurred during the whole trip, you will get the average speed. Cite APA 7 ,. Difference Between Similar Terms and Objects.
