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
photons and gravity it is observed that light is affected by gravity we can recognize the gravitational behaviour of light from the fact that
the phase of weightlessness may be observed in the following situationsi when objects fall freely under gravity for example a lift goes down freely
the weight of a body is the force with which it is attracted in the direction of the centre of earth when an object is stationary with respect to the
