Answer : In Physics, velocity refers to the speed of any object that is moving in a certain direction. Velocity (SI unit: meter per second) is the rate of change in the position of any object and the change is measured concerning a frame of reference and time. To calculate the velocity of any object, both the speed and direction are required and therefore, it can be identified as a vector quantity.
Now, uniform velocity is referred to the condition where a body covers an equal distance in an equal time interval. It can be said that an object is moving in uniform velocity if that object moves in a fixed direction and it is witnessed that it is successful to cover equal displacements in equal intervals of time regardless of the fact of how small those time intervals are. In the equation, it can be expressed as (d = v t). here, d represents distance, t means time and v stands for velocity.
The uniform velocity is a very stable form of velocity which essentially means that it does not change with time intervals. If a bus driver can cover equivalent distances at equivalent intervals of time, the same will happen over and over again and we can say that the movement of the bus has a uniform velocity that is stable and will not alter easily.
Examples of uniform velocity
Some of the most popular examples of uniform velocity are as follows:
- The movement of all the hands in any clock.
- The rotation of the Earth.
- The revolution of the earth around the Sun.
- Raindrops fall on the ground from the clouds at uniform velocity.
- Any type of circular motion is also a good example of uniform velocity like a revolving fan.
