Question

State Newton's second law of motion.Give its mathematical expression also.State one application of this law.​

Answer 1

Answer:

Newton's second law of motion:

Newton's 2nd law of motion states that the rate of change of momentum of a body is directly proportional to the force applied on it, and the momentum occurs in the direction of the net applied force.

Explanation:

mathematical expression:

Newton's second law = F = m * (V1 - V0) / (t1 - t0) The change in velocity divided by the change in time is the definition of the acceleration a. The second law then reduces to the more familiar product of a mass and an acceleration: F = m * a.

Example:

Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

Answer 2

Answer:

The 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.

Mathematical expression:

F=ma or force is equal to mass times acceleration

Application of this law in real life:

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.
