Define force and write its si. Unit
Inphysics, aforceis any influence that causes anobjectto undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force can cause an object withmassto change itsvelocity(which includes to begin moving from astate of rest), i.e., toaccelerate, or a flexible object todeform, or both. Force can also be described by intuitive concepts such as a push or a pull. A force has bothmagnitudeanddirection, making it avectorquantity. It is measured in theSI unitofnewtonsand represented by the symbolF. it's formulae is f (force)=ma(mass x acceleration)
Aforceis a push or pull upon an object resulting from the object'sinteractionwith another object. Whenever there is aninteractionbetween two objects, there is a force upon each of the objects. When theinteractionceases, the two objects no longer experience the force. Forces onlyexist as a result of an interaction.
Its S.I unit is Newton ( N )
