teaching forces 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..

Force - 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 te..

Force is the external agent that changes the state of rest or uniform motion of a body along a straight lin..

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..

In many cases when we pull or push an object, we find that force and displacement are not in the same direction. Let a constant force F acting on a body produce a displacement S as shown in the figure. Let q be the angle between the directions of the force and displace..

Kinematics deals with the study of motion without taking into account the cause of motion.Dynamics is concerned with the cause of motion, namely force..

Introduction - In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behaviour of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinematics and Dynamics. Kinematics deals with the study ..
