W = FS cos q If the displacement S is in the direction of the force F, q = 0, cos q =1 Then, W = FS x 1 W = FS If q = 90 o , cos 90 o = 0 Therefore, W = FS x 0 = 0 i.e, no work is done by the force on the body. If a stone tied at the end of a string is whirled around i..

Motion of a Body in a Horizontal Circular Orbit - Some examples of horizontal circular motion are planetary motion (which may or may not be circular), merry-go-round and motion of electrons around the nucleus. There is one thing ..

When vehicles go through turnings, they travel along a nearly circular arc. There must be some force which will produce the required acceleration. If the vehicles go in a horizontal circular path, this resultant force is also horizontal. Consider the si..

Friction is not always reliable at circular turns if high speeds and sharp turns are involved. To avoid dependence on friction, the roads are banked at the turn so that the outer part of the road is somewhat lifted up as compared to the inner part. The surface of road and hence..

An object moving along a circular track with uniform speed is an example for a non - uniform motion because the direction of motion of the object goes on changing at every instant of tim..

In the example discussed under the topic uniform and non-uniform motion we have classified motion along circular track as an example of non-uniform motion. Let us now see why circular motion is considered as non-uniform motion. T..

Uniform Circular Motion - The revolution of moon around the Earth and the revolution of an artificial satellite in a circular orbit round the Earth are examples of circular motion. Consider a particle moving with constant speed along the circumferen..

Force And Motion - A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion. In all the above ex..
