What is force ? what is the SI unit of force.
Answers
Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
newton
newtonThe SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m.
Force is described as the push or pull on an object and force Is a vector quantity.
SI unit of force is Newton.
Force is classified into two category:-
1.
Contact force is further divide into following type of forces:-
●Muscular Force
●Frictional Force
●Normal Force
●Applied force
●Tension Force
●Spring Force
●Air resisting Force
2
Non-contact force further divided into following types of forces:-
●Gravitational Force
●Magnetic Force
●Electrostatic Force
Force is equal to mass multiplied by acceleration.
