what is a real life example of Newton's 2nd and 3rd Law?

Answer 1

Example of 2), where F = ma: Man with big arm and large force accelerates bowling ball to a strike. Child with small arm and little force accelerates bowling ball to a roll that keeps everybody waiting.

Example of 3), where "Every action has an equal and opposite reaction":
Man on ice skates throws his partner away from him, and finds himself going backwards.

Answer 2

The three laws are easily demonstrated using a pool table. In this case the second law, F=mA, can be demonstrated by pointing out that the harder you hit the cue ball (the greater the applied F) the faster it accelerates and moves. The third law can be demonstrated by showing how when the cue ball hits another ball there will be an equal and opposite reaction, depending on the vectors involved. Pool is a game of Newton's laws, use it as an example.

Answer 3

First regulation - merchandise in action has a tendency to stay in action till an outdoors stress acts on it. evaluate a baseball that you in user-friendly words hit - that's flying with the help of the air. Now, if there become no air or gravity, it would want to proceed alongside an same direction till it hit some thing else. regrettably for the baseball (yet luckily for the outfielders), friction (the air resisting the ball's passage) is slowing it down, and gravity is pulling the ball in direction of the earth (and, minutely, the earth in direction of the ball). second regulation - stress equals mass cases acceleration (F=ma). evaluate that baseball lower back. The stress with which it leaves your bat is an same because the speed of your bat cases the load of the bat cases the speed of the ball cases the load of the ball, with some different factors (gravity, friction, the "springiness" of the bat and ball)... 0.33 regulation - for each action there is an equivalent and opposite reaction. Blow up a balloon. keep the neck pinched closed. Now launch the neck. The balloon flies away because the air is forced out the neck - air is going one way, balloon is going the different.
