Question

Proof :- Newton's Second law of motion​

Answer 1

Answer:

Newton's second law of motion states that the rate of change of momentum of an object is Proportional to the applied unbalanced force in the direction of force. Suppose an object of mass, m is moving along a straight line with an initial velocity, u. ... The quantity, k is a constant of proportionality.4

Explanation:

Examples of Newton's 2nd Law  If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.

Answer 2

Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.

ie., F=ma

Where F is the force applied, m is the mass of the body, and a, the acceleration produced.

What will happen if a body is subject to multiple forces at the same time?

If a body is subjected to multiple forces at the same time, then the acceleration produced is proportional to the vector sum (that is, the net force) of all the individual forces.
