force is an external effort in the form of a push or pull which either changes or tends to change the state of rest or of uniform motion in a straight line.motion is in a straight line.force is needed to change the state of rest or of uniform motion.force is effort....!!!------------------------------------------------------------------------------------------------------------------------INERTIA this footballer is applying force on the ball to change its state of rest....!!footballer is applying an external force to change the direction and the speed of the moving body............!!!so inertia is the inherent property of all the objects to not to change

Forces : pushes and pulls We can't actually see forces, but we see their effect on objects. We see the Moon orbit the Earth, objects fall to the ground, and birds fly - all of these are because of forces. " src="http://www.darvill.clara.net/enforcemot/graphics/arrowanm.gif" width=32 align=absMiddle border=0> A force is a push or a pull. We measure forces in "Newtons" (N)named after Newton (1642 - 1727). 1 Newton isn't a very big force: it's about the weight of an apple. Forces are Vectors, because the direction is important. Forces can change:- the speed of an object the direction that an obj

CENTRIFUGAL FORCE -THE FALSE FORCE An evil word has worked its way into our daily vocabulary, and with it, an incorrect understanding of the way physics works. "Centrifugal force ( Latin for "center fleeing") is often used to describe why mud gets spun off a spinning tire, or water gets pushed out of the clothes during the spin dry cycle of your washer. It is also used to describe why we tend to slide to the outer side of a car going around a curve. It is a common explanation...the only problem is all of it is absolutely wrong!!! Centrifugal force does not exist...there is no such thing...it is a
