Question

What is speed? Name its types.

Answer 1

Explanation:

1. The rate of change of position of an object in any direction is called the speed of that object.
2. There are four types of speed which are uniform speed, variable speed, average speed, and instantaneous speed.
3. Uniform speed: If an object covers an equal distance in an equal interval of time it is moving with a uniform speed.
4. Variable speed: If the speed of a body is changing with respect to the time it is moving with a variable speed. It is also known as non-uniform speed.
5. Average speed: Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance.
6. Instantaneous speed: The instantaneous speed is the speed of an object at a particular moment (instant) in time.
