Question

what are the different types of speeds and explain them​

Answer 1

The rate of change of position of an object in any direction.

There are four types of speed and they are:

Uniform speed

Variable speed

Average speed

Instantaneous speed

Uniform speed: A object is said to be in uniform speed when the object covers equal distance in equal time intervals.

Variable speed: A object is said to be in variable speed when the object covers a different distance at equal intervals of times.

Average speed: Average speed is defined as the uniform speed which is given by the ratio of total distance travelled by an object to the total time taken by the object.

Instantaneous speed: When an object is moving with variable speed, then the speed of that object at any instant of time is known as instantaneous speed.

Measurement of Speed:

For the measurement of speed in vehicles, speedometers are used. To measure the distance covered odometers are used. Speed can also be calculated with the help of a graph. The Distance-time graph helps in understanding the speed of an object.

Answer 2

Answer:

There are 4 types of speed:-

1. Uniform speed : if it covers covers equal distances in equal intervals of time.
2. Variable speed: A variable speed is a component of high- performance residential furnaces and air handles.
3. Average speed: It is calculated by dividing the total distance that something has travelled by the total amount of time it took it to travel the distance.
4. Instantaneous Speed: It is a speed of a object at a particular movement in a time.
