Is centre of mass same as the centre of gravity of a body? How can a rigid body be balanced?

Define centre of mass. Find the centre of mass of a triangular lamina.

What is mass of a body?

The weight of a body of mass 1 kg

How can the velocity of a body be changed?

Give the location of the centre of mass of a (i) sphere, (ii) cylinder, (iii) ring, and (iv) cube, each of uniform mass density. Does the centre of mass of a body necessarily lie inside the body?

What is centre of mass? Show that centre of mass of a system of particles is defined as the point whose position vec is given by vecR = frac(Sigmam_1vecr_)(M)

Can the velocity of a body negative or zero ?

From a uniform disk of radius R, a circular hole of radius Rl 2 is cut out. The centre of the hole is at RI2 from the centre of the original disc. Locate the centre of gravity of the resulting flat body.

What is KE of rotation of rigid body ?
