Question

Explain newton's second law of motion with example?

Answer 1

Hi

The rate of change of momentum of a body is directly proportional to the force applied on it and the change takes place in the direction of the applied force.

Hope this helps :)

Answer 2

Here's your answer..


●Newton's second law of motion:-
According to Newton second law of motion,the Raye of change of a body/object is directed proportional to force applied to it and takes place in the direction in which the force acts.


◆Force =Mass ×Acceleration
◆Acceleration =Force/Mass


●The Acceleration produced by the body/object is directly proportional to the Force and it is inversely proportional to the mass of the body/object.


●Since ,the Acceleration produced is inversely proportional to the mass of a body so if the mass of a body is doubled ,it's Acceleration will be halved and if the mass is halved then Acceleration will get doubled .


●Since,the Acceleration produced is inversely proportional to the mass of the body ,it means that it will be easier to move light bodies then heavy bodies.


Now,Come to the Examples:-

◆You may have noticed that while catching the faster moving cricket ball,a fielder often pulls his hand backward with the moving ball.

Why?

This is because In doing so,the fielder increases the time during which the high velocity if the moving ball decreases to zero.
Therefore,the Acceleration of the ball is decreases and therefore impact of catching the faster moving ball is also reduced and fielder did not get hurt in his hand.



◆You may have also seen In the case of high jump ,a athelete is provided either a cushion or a help of same on the ground to call.
A help of same reduced the large Momentum of a falling 'high jumping athelete '.And due to this the rate of changed of Momentum of athelete os less due to which a smaller stopping for ex acts on the athelete and they does not get hurt.
