Force is a push or a pull that tends to change the state of uniform motion of an object.
A force can cause an object to accelerate, slow down, remain in original shape or change shape.
A force while acing on a body may :
A force can cause an object to accelerate, slow down, remain in original shape or change shape.
A force while acing on a body may :
- Change the motion of a body
- Retard the motion of a body
- Balance the forces already acting on a body
- Give rise to the internal stresses in a body
In order to determine the effects of a force acting on a body, one must know the following characteristics of the forces.
- The magnitude of the force
- The line of action of the force
- The nature of the force
- The point at which force is acting
The magnitude of the force is given by in MKS system - kilogram-force ( kgf ) and in SI system - Newton ( N ).
1 kgf = 9.81 N
There are different types of force. You can check it out below :
- Applied force
- Gravitational force
- Normal force
- Frictional force
- Air resistance force
- Tension force
- Spring force
