Question

Explain how you should catch a ball with newtons 2nd law

Answer 1

Newtons Second Law
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

F= M x A
Force = Mass x AccelerationCatching a Cricket Ball
When a cricket ball is hit with a greater amount of force the harder it becomes to actually catch the ball

In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly he risks breaking fingers or dropping the ball.


Catching the Ball
As a result of this the fielder has to apply a larger force to stop the ball. Thus, if he tries to stop a fast moving cricket ball the fielder may get hurt as the ball exerts a great pressure on the hands but if he tries to stop it gradually by moving his arms back then the velocity decreases gradually in a longer amount of time.

Newtons Second Law
Applying it to Newtons Second Law
When the ball is hit hard it becomes harder for the catcher to catch it as the ball is going at a faster speed

When the ball is hit softer it becomes easier for the catcher to catch the ball as the ball is going at a slower speed
