Q4 of 25 Page 130

What are the common gadgets based on Newton's second law of motion?

Newton’s second law is:

The rate of change of momentum of body is directly proportional to force acting on it.


Example, a crickter acting as a fielder lowers his hand to catch the ball, to reduce the impulse (shown in picture below)



The common gadgets which are based on Newton’s 2nd law of motion:


i. Air bags: The air bags reduce the effects of force in a forward motion.


ii. Seat belts: A seat belt controls the motion of our upper body with the belt so that when the car stops, we do not hit our head.
