Displacement OF Objects When Centre OF Mass is at Rest

Displacement OF Centre OF Mass

Displacement OF Centre OF Mass

Special Cases Of Centre Of Mass At Rest

Statement-1 : The centre of mass of a proton and an electron, released from their respective positions remains at rest. tatement-2 : The centre of mass remains at rest, if no external force is applied

Two persons A and B of weight 80 kg and 50 kg respectively are standing at opposite ends of a boat of mass 70 kg and length 2 m at rest. When they interchange their positions then displacement of the centre of mass of the boat will be :-

Two point objects of mass 1.5 g and 2.5 g respectively are at a distance of 16 cm apart, the centre of mass is at a distance x from the object of mass 1.5 g. Find the value of x.

What will be the distance and displacement of the object when it makes one complete round of a circular park of radius 5m?

The rate of change of angular momentum of a system of particles about the centre of mass is equal to the sum of external torque about the centre of mass when the centre of mass is :
