Question

applications of newton 1st and 2nd law.

Answer 1

If a body is at rest ,it remains at rest unless a force is applied on it ."" If a body is moving ,it will continue to move with the same speed in the same direction unless a force is applied on it" Newton put the above observation in the form of a law which is called the Newton's first law of motion.

Newton's 2nd Law  The second law of motion states that acceleration is produced when an unbalanced force acts on an object (mass). ... 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

Answer:

A fielder pulls his hand backward; while catching a cricket ball coming with a great speed, to reduce the momentum of the ball with a little delay. According to Newton's Second Law of Motion; rate of change of momentum is directly proportional to the force applied in the direction.
