Can the relative velcity ot two bodies be greater than the absolute velcity of either body.

Assertion: Relative velocity of A w.r.t B is greater than the velocity of either, when they are moving in opposite directions. Reason: Relative velocity of A w.r.t B=vecv_(A)-vecv_(B)

Statement-1 : The relative velocity between any two bodies moving in opposite direction is equal to sum of the velocities of two bodies. Statement-2 : Sometimes relative velocity between two bodies is equal to difference in velocities of the two.

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

Assertion: Density of hollows body is always less than the density of substance of equal mass of the body. Reason: Volume of hollow body is greater than the volumeof substance of the body. But mass of hollow body is equal to mass of substance of the body.

Why is the speed in general, greater than the magniude of the velcity ?

When the velcity of flow of liquid is greater than critial velocity, the liquid is said to have

The ratio of relative velocity of separation after collision to the relative velocity of approach before collision between two colliding bodies is ____________.

When distant between the centres is less than sum of radii and greater than their absolute difference.
