Force
------------------------------------------------------------------------------------------------------
Force is defined as push or pull.
The SI unit of force is newton which we denote as capital N.
Now question is:
What is push or pull.
A force which moves a body away from the point of application of force is called push.
A force which moves a body closer to the point of application of force is called pull.
Effects of Force?
1. A force can cause a motion in stationary object.
2. A force can stop the moving body objects or slow them down.
3. A force can make a moving object move faster.
4. A force can change direction of moving objects.
5. A force can change the shape of objects.
Approved that:
Force is an external agent which can changes or tends to change the state of rest or uniform motion of the body or changes its direction.
Forces in Nature:
1. Muscular force
2. Mechanical force
3. Gravitational force
4. Electrical force
5. Magnetic force
Units of force:
1. The commonly used for measuring force is called kilogram force (symbol=kgf).
2. The force of gravity acting on one kg mass is one kgf.
3. One gram force (1 gf) is the force required to lift a mass of 1 g vertically upward.
How force is measured:
Force is measured by spring balance.
