Question

What is relative velocity? Explain it in the case of one dimensional motion.​

Answer 1

Answer:

Relative velocity of one object w.r.t. another is the velocity with which one object moves w.r.t. another object.

One dimensional motion:

When two objects are moving along parallel straight lines in the same direction, the magnitude of relative velocity of one object w.r.t. the other is equal to the difference in magnitude of two velocities.

When the two objects are moving along parallel straight lines in opposite directions, the magnitude of relative velocity of one object w.r.t. other is equal to the sum of the magnitude of their velocities.

Answer 2

Explanation:

Relative velocity of one object w.r.t. another is the velocity with which one object moves w.r.t. another object.
