Force
Force
In our everyday life, we observe that some efforts are required to put a stationary object into motion or to stop a moving object.
Force:
A pull or push over an object because of its interaction with other object is called force. For example:
1. To open a drawer, one has to pull it; and to close the drawer one has to push it. Thus, in both the conditions a person applies force by pull or push.
2. To kick a ball, one has to push it, i.e. a force is applied.
3. To ride a bicycle one has to push the pedal. In this condition, force is applied while pushing the pedal.
Direction and Magnitude of Force:
While plucking an apple from a tree we pull the apple towards ourselves. Hence we exert FORCE on that object. This also means that force has direction. Also, you push or pull an object gently or hard. This means force has a magnitude. Any action which causes pull, hit or push on a body is called force. Force cannot be seen but it can be judged only by the effects which it produces in various bodies around us.
The SI unit of force is Newton “N”.
Force can produce acceleration in the body on which it acts. When you apply the brakes in your bicycle, you are changing its velocity. Similarly, suppose you press the bulb of a dropper. You are producing a change in the shape of the bulb
State of Rest: An object is called in the state of rest when it is not moving. This means a stationary object is called in the state of rest. For example: a building, an electric pole, a ball kept over the ground and not moving, etc.
State of Motion: A moving object is called in the state of motion. For example – a moving car, a moving ball, etc. A force can speed up a moving object. Force can decrease the speed of a moving object. Force can stop a moving object. Force can change the direction of a moving object. Force can move a stationary object.
In which of the following cases the net force is zero ? a) A car drives around a circular race track at a constant speed b) A person holds the door to enter the room c) A ball, rolling across a grassy field, slowly comes to a stop | |||
