FORCES AND LAWS OF MOTION NOTE BY PLANCESS

It is the force that enables us to do any work. To do anything, either we pull or push the object. Therefore, pull or push is called force. Example: to open a door, either we push or pull it. A drawer is pulled to open and pushed to close.


Force can make a stationary body in motion. For example a football can be set to move by kicking it, i.e. by applying a force. Force can stop a moving body: For example by applying brakes, a running cycle or a running vehicle can be stopped.

Force can change the direction of a moving object. For example; By applying force, i.e. by moving handle the direction of a running bicycle can be changed. Similarly by moving steering the direction of a running vehicle is changed.

Force can change the speed of a moving body: By accelerating, the speed of a running vehicle can be increased or by applying brakes the speed of a running vehicle can be decreased. Force can change the shape and size of an object. For example: By hammering, a block of metal can be turned into a thin sheet. By hammering a stone can be broken into pieces.
