Question

Force is defined as
1. change in momentum
2. rate of change of momentum
3. the quantity that opposes inertia
4. the quantity that keeps the velocity constant

Answer 1

Force is defined as RATE OF CHANGE OF MOMENTUM.

• Force is a vector quantity characterized by the product of mass and acceleration vector of the object.

• However, as per NEWTON'S 2ND LAW OF MOTION, force is define as the rate of change of linear momentum with respect to time.

Mathematically, it is written as :

$\boxed{P = \dfrac{\Delta F}{\Delta t}}$

• That is why we say : Higher the rate of change of momentum, higher will be the force, and vice-versa.

• OPTION 2) IS CORRECT ✔️.
