for a very every case the moment of inertia of a one particle about an axis is given by i mr2 here m is the mass of the particle and r its
like the centre of mass the moment of inertia is a function of a body that is concurrent to its mass distribution moment of inertia gives a
the rate of change of angular velocity with related to time is known as angular
the power of change of angular displacement with respect to time is known as angular
translational if a body goes such that its orientation does not change with respect to time then body is said to move in translational motionrotation
a rigid object is a body with a exact and unchanged size and shape ie a body is said to be rigid if the distance among any two particles of the body
when two objects collide like there velocities are not in the line of action of contact force then the collision is known as oblique collisionwe can
elastic collision a collision is known as elastic when kinetic energy is also conserved along with the linear momentum there is no transformation or
when two particles tend to each other their motion alters or their momentum modify because of their mutual interactions this phenomenon is called as
each physical system has related with it a certain point whose motion characterizes the motion of the whole system when the system goes under some
