Answer:
"second law of motion:- the force applied on a body is equal to the product of mass of the body and the acceleration produced in it.eg., F= ma " the second law of motion gives the definition of force force is any influence that causes an object to undergo a certain change either concerning its moment direction and geometrical structure as a unit of force is Newton (N). linear momentum,:- the product of the mass at the velocity e of a body is called the linear momentum of the body. it is a vector quantity its unit is kg-m/,s. therefore linear momentum =Mass × Velocity a heavier body has a larger inner momentum than a lighter body moving with the same velocity. in the absence of external forces the total linear momentum of the system remains conserved.1021 bhai absolutely right mathematics expression . deya haa
