hii what is relative velocity
Answers
Answer:
Relative Velocity:
We encounter occasions where one or more objects move in a frame which is non-stationary with respect to another observer.
For example, a boat crosses a river that is flowing at some rate or an airplane encountering wind during its motion. In all such instances, in order to describe the complete motion of the object, we need to consider the effect that the medium is causing on the object. While doing so, we calculate the relative velocity of the object considering the velocity of the particle as well as the velocity of the medium. Here, we will learn how to calculate the relative velocity.
Let us consider two objects, A and B moving with velocities Va and Vb with respect to a common stationary frame of reference, say the ground, a bridge or a fixed platform.
The velocity of the object A relative to the object B can be given as,
Vab=Va−Vb
Similarly, the velocity of the object B relative to that of object a is given by,
Vba=Vb−Va
From the above two expressions, we can see that
Vab=−Vba
Although the magnitude of the both the relative velocities is equal to each other. Mathematically,
|Vab|=|Vba|
