Relative Motion | Velocity of Approach

Relative Motion in 1D

Relative Motion In Plane

Introduction to Relative Motion || Relative Velocity || Relative Acceleration

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

Show that in a perfectly elastic collision , the relative velocity of seperation after collision is equal to relative velocity of approach before collision .

In one-dimensional elastic collision, the relative velocity of approach before collision is equal to

Show that in case of one dimensional elastic collision of two bodies, the relative velocity' of sepa¬ ration after the collision is equal to the relative velocity of approach before the collision

In two separate collisions, the coefficient of restitutions e_(1) and e_(2) are in the ratio 3 : 1 . In the first collision the relative velocity of approach is twice the relative velocity of separation. Then, the ratio between relativevelocity of approach and relative velocity of separation in the second collision 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.
