Question

define force state s i unit of force on what factors for the force depends

Answer 1

Here's the answer:

》 A force is an agenct that changes the shape or state of motion of a body or tries to change it.

》The S.I unit of force is Newton (N).

》 Factors on which force depends:

1). The direction in which the force is applied.
2) The magnitude of force applied.
==================================

•Additional information: Force is classified into two groups:
1). Contact force- frictional force, tension force,etc.

2). Non-contact force- gravitational force, electrical force, magnetic force,etc.

Answer 2

Heya......!!!!

___________________________

Simply we can say that Force is a Push or Pull .

=> Force can change the state of rest or of uniform motion of body , i.e Force is reason behind the cause of translatory motion .

=> Force is the interaction between the object and other object ( Source ) .

=> Force is a Vector quantity .

=> SI unit of Force is = Newton ( N )

=> CGS unit of force is = Dyne .

-----------------------------------------

F = dp / dt

p = mv

=> F = d / dt ( mv )

=> F = mdv / dt + vdm / dt

As m is the mass of body and mass is constant then dm / dt = 0 .

=> F = m dv/dt

*( dv / dt = a , acceleration ) .

➡ F = ma .


Effects produced by Force :-

1.) A force can move a object at rest.
2 ) A force can stop a moving body
3.) A force can change the direction of moving body .
4 ) A force can change the shape and size of object .
5.) A force can change the speed of moving body.


A force is depended on the direction in which force is applied and also the amount of force applied .
