forces and motion experiments

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..

Couple two spring balances A and B as shown in the figure. When we pull the balance B both the balances show the same reading indicating that both the action and reaction forces are equal and opposit..

Is Newton's third law of motion applicable to gravitational force? Yes it is. Let us now see how Newton's third law of motion is applicable to the gravitational force existing between the various objects in the universe. According to Newton's third law of ..

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..

Is the push/pull which changes or tends to change the state of rest or uniform motion in a straight line. It is a vector quantity, i.e., it has both magnitude and directio..

A force is often defined as a "push" or a "pull". There is nothing untrue with this statement, but does not really tell you much about a force. Instead of defining force, it substitutes an antonym. A physicist prefers to define a force in terms of what it doe..

According to Newton's first law of motion every body continues to be in its state of rest or uniform motion along a straight line unless an external force acts on it. This means that a ball moving on a horizontal surface should continue to move indefinitely as no ..

Introduction - We have learnt about the motion of objects based on the definition of displacement, velocity and acceleration. Now let us see the causes that influence the motion of bodies. Have you wondered why certain natural phenomena occur and why they continue to occur in th..
