Motion

A body may be considered to be made up of an indefinitely large number of particles, each of which is attracted towards the centre of…

Let consider the motion of the centre of mass of the Earth and moon system (Figure). The moon moves round the Earth in a circular…

In translator motion of a body; every particle experiences equal displacement with time; therefore the motion of the whole body may be represented by a…

Math prob (a): The driver of a car travelling at 72 kmph observes the light 300 m ahead of him turning red. The traffic light…

Elastic Collision: If the kinetic energy of the system is conserved during a collision, it is called an elastic collision. The total kinetic energy before…

A collision between two particles is said to occur if they physically strike against each other or if the path of the motion of one…

Conservative forces: If the work done by a force in moving a body between two positions is independent of the path followed by the body.…

When the centripetal force is greater than the frictional force, skidding occurs. If μ is the coefficient of friction between the road and tire. then…

According to Newton’s third law of motion, for every action, there is an equal and opposite reaction. The equal and opposite reaction to the centripetal…

Any force like gravitational force, frictional force, electric force. magnetic force etc. may act as a centripetal force. Some of the examples of centripetal force…
