In which condition the relative velocity of two objects is the maximum?
This will be at its highest when two bodies are approaching each other and at its lowest when two bodies are moving apart in the same line. When two bodies approach, the relative velocity is the sum of the two velocities, and it is the highest.
What is meant by relative velocity?
Definition of relative velocity : the vector difference between the velocities of two bodies : the velocity of a body with respect to another regarded as being at rest — compare relative motion.
What is relative velocity mention the expression for relative velocity?
Relative velocity is a difference in velocities of two objects where one is at rest with respect to another. For example: Motion of aeroplane in wind and moving boat in water. It can be expressed as V = Vab + Vbc when two bodies are in same direction.
Can relative velocity of two bodies be greater than absolute velocity of either explain your answer by example?
Yes, when two bodies move in opposite directions, the relative velocity of each is greater than the individual velocity of either body .
What is relative velocity derive the expression for it?
Relative Velocity Formula – Derivation Here [XB(0) – XA(0)] = distance of the object B from object A at time t = 0. [XB(t) – XA(t)] = distance of the object B from object A at time t. This equation gives the velocity of object B relative to object A.
What is velocity and relative velocity?
The difference between velocity and relative velocity is that velocity is measured with respect to a reference point which is relative to a different point. While relative velocity is measured in a frame where an object is either at rest or moving with respect to the absolute frame.
What is the equation for relative velocity?

How can the relative velocity of two bodies be greater or lesser than the absolute velocity of the either body?
Can the relative velocities of two bodies be greater than the absolute velocity of either body? Yes, when two bodies move in opposite directions, the relative velocity of each is greater than the individual velocity of either body .
What is relative velocity?
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,…
What is the general formula of velocity?
The general formula of velocity is : Velocity of B relative to A is = This is the only formula that describes the concept of relative velocity. When two objects are moving in the same direction, then
What is the relative velocity of the plane with respect to ground?
The relative velocity of the plane with respect to the ground can be given as. The angle between the velocity of the wind and that of the plane is 90°. Using the Pythagorean theorem, the resultant velocity can be calculated as, R 2= (100 km/hr) 2 + (25 km/hr) 2.
What is the velocity with respect to A and B and C?
V AB is the velocity with respect to A and B, V BC is the velocity with respect to B and C and V AC is the velocity with respect to A and C. Problem 1: A train travels with a speed of 70m/s with regards to the ground in the east direction. A spectator is moving with a speed of -15m/s with regards to the train in the west direction.
