Question

Newton’s second law of motion gives a measurement of:
(a) Inertia
(b) Momentum
(c) Force
(d) Acceleration

Answer 1

Hint: As the question talks about Newton's second law of motion, so, we will understand its concept. Also, we will use the fact that if no force is applied to any object then, acceleration is zero. This fact will be helpful in choosing the right option.

Formula used: $F=ma$ where F is the force, a is acceleration and m is mass of an object.

Complete step by step answer:
Newton’s second law of motion says about the motion in which both mass of an object as well as its acceleration is included. The formula used under this law is $F=ma$ where F is the force, a is acceleration and m is mass of an object. By this formula we can easily assume that the acceleration of any object which is produced by any force applied on it is directly proportional to magnitude of the net force and the same acceleration is inversely proportional to the mass of the object. This means that if there is an increase in the force applied on any object, it will result in the increase in the acceleration of that object. But this law measures force in particular, as its basic definition is the force applied on an object equal to the product of mass and acceleration of that object.

So, the correct answer is “Option C”.

Additional Information: Inertia focuses on the tendency of an object to remain constant while the momentum is a motion of a body in motion. The momentum is a measurement of mass and velocity of an object.

Note: The important points to be noted for this question are:
(1) One should learn the definition of Newton's second law.
(2) One should not get confused between the terms used here as acceleration and force and mass. This law should not be seen under acceleration for the measurement but basically it gives the measurement of force.
(3) Until and unless we do not apply force to any material it will not move resulting into zero acceleration.
