Relative velocity is the velocity of an object with respect to another object. It takes into account the motion of both objects and is dependent on the observer's frame of reference.
Relative velocity is calculated by subtracting the velocity of one object from the velocity of another object. The resulting value is the relative velocity between the two objects.
Absolute velocity is the velocity of an object with respect to a fixed point, while relative velocity takes into account the motion of both objects and is dependent on the observer's frame of reference.
Yes, relative velocity can be negative. A negative relative velocity indicates that the two objects are moving in opposite directions.
Relative velocity plays a crucial role in determining the outcome of collisions between objects. The relative velocity between two objects at the moment of collision can determine whether the collision is elastic or inelastic, and can also affect the magnitude and direction of the resulting velocities after the collision.
