Question

what is force write its si unit ?​

Answer 1

Explanation:

in physics , a force is. any Interaction that, when unopposed, will change the motion of an object ..

force is also described intuitively as push or pull.

a force has both magnitude and direction, making its vector quantity.

si unit of force is newtons.

|| Types of forces ||

Generally we categoise forces in two types:

$\large \tt \purple { Contact \: forces}$

• A contact force is a force between two objects or the force between an object and surface that are in contact with each other.

• Muscular force, mechanical force and frictional force are contact forces.

➠$\rm\green { Muscular \: Force}$ :The force exerted by the muscles of the body.

➠$\rm\green { Mechanical \: Force}$ : The force produced by a machine.

➠$\rm\green { Frictional \: Force}$ : The force that opposes the motion of an object.

$\large \tt \purple { Non-Contact \: forces}$

• Force which don't involve physical contact between two bodies on which they act is called non-contact force.

• Magnetic force, electrostatic force, gravitational force are non-contact forces.

➠$\rm\green { Magnetic \: Force}$ : A magnet exerts a non-contact force on objects made of iron, cobalt or nickel.

➠$\rm\green { Electrostatic \: Force}$ : This force is exerted by a charged body on another charged or uncharged body.

➠$\rm\green { Gravitational \: Force}$ : The force that exists between any two masses because of their mass.
