04. State and prove Newton's second law of motion?
Answers
Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Explanation:
The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time.
Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .
Newton's second law of motion states that the force applied to the system is equal to the time rate of change of momentum.
So, F= dt/dP
But P=mv
So, F= dt/d(mv)
Or F=m dt/dv
⟹ F=ma
