Relative Velocity

STATEMENT-1 The dimensional formula for relative velocity is same as that of the charge in velocity STATEMENT-2 [Relative velocity] = [Change in velocity] STATEMENT-3 In addition or subtraction of two physical quantities of same dimension, the result also have same dimensIon only.

Statement-1 : Rain is falling vertically downwards with velocity 6 km/h. A man walks with a velocity of 8 km/h. Relative velocity of rain w.r.t. the man is 10 km/h. Statement-2 : Relative velocity is the ratio of two velocities

The vector difference between the absolute velocities of two bodies is called their relative velocity. The concept of relative velocity enables us to treat one body as being at rest while the other is in motion with the relative velocity. This jormalism greatly simplifies many problems. If vecv_(A) is the absolute velocity of a body A and vec_(B) that of another body B then the relative velocity of A in relation to B is vec_(AD)=vecV_(A)-vecv_(B) and vecv_(BA)=vecv_(B) - vecv_(A) . The principle follows here is that the relative velocity of two bodies remains unchaged if the same additional velocity is imparted to both the bodies. A simple way of carrying out this operation is to be represent the velocities in magnitude and direction from a common point. Then the line joining the tips of the vectors represents the relative velocity Q A train A moves to the east with velocity of 40 km/hr and a train B moves due north with velocity of 30 km/hr. The relative velocity of A w.rt. B is

Three blocks shown in move vertically with constant velocities The relative velocity of w.r.t C is 100m//s upward and the relative velocity of B w.r.t A is 50m//s downward. All the string are ideal The velocity of C with respect to ground is 125//x calculate x .

A person crossing a road with a certain velocity due north, sees a car moving towards east.The relative velocity of the car w.r.t the person is sqrt2 times that of the velocity of the person.The angle made by the relative velocity with the east is

Two particles of mass 1 kg and 3 kg move towards each other under their mutual force of attraction. No other force acts on them. When the relative velocity of approach of the two particles is 2m//s, their centre of mass has a velocity of 0.5 m/s. When the relative velocity of approach becomes 3 m/s. When the relative velocity of approach becomes 3m/s, the velocity of the centre of mass is 0.75 m/s.

two train A and B are moving on parallel tracks with velocities of 60 kmh^(-1) and 90kmh^(-1) respectively but in oppiste directions. Find (i) the relative velocity of train A.w.r.t train B and (ii) the relative velocity of ground w.r.t tain A.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five responses. Reason: For inelastic collision, 0leelt1 . Hence, the magnitude of relative velocity of separation after collision is less than relative velocity of approach before collision.
