The correct answer is option(2) i.e. Force = mass × acceleration.
Explanation:
Newton's second law is often stated as F = ma , which means the force (F) acting on an object is equal to the mass (m) of object times its acceleration (a) This means the more mass an object has , the more force you need to accelerate it, and the greater the force, the greater the object's acceleration.
Force(F) = Mass(m)× Acceleration(a).
Unit of Force = SI unit of Force is in Newtons (N) .
1 Newton is equal to 1 kg*m*s-2.
Acceleration of an object is directly related to the net force and inversely related to its mass.
Acceleration of an object depends on two things, force and mass.
Mass is a measure of the amount of matter in an object .
Mass is usually measured in grams (g) or kilograms (kg).
An object's mass is constant in all circumstances, contrast this with its weight, a force that depends on gravity.
