what are real life examples of newtons 3 laws of motion?

Answer 1

(1) A baby in motion tends to stay in motion when the car crashes

until

(2) Its car seat or the windshield exert a force on it and make it stop.

(3) When the car hits the baby, the baby hits the car back with the same force. The car is a little bigger, though, so its velocity doesn't change much. The baby's velocity changes a lot.

Answer 2

First Law - object in motion tends to stay in motion until an outside force acts on it.

Consider a baseball that you just hit - it's flying through the air. Now, if there was no air or gravity, it would continue along the same path until it hit something else. Unfortunately for the baseball (but fortunately for the outfielders), friction (the air resisting the ball's passage) is slowing it down, and gravity is pulling the ball toward the earth (and, minutely, the earth toward the ball).

Second Law - Force equals mass times acceleration (F=ma).

Consider that baseball again. The force with which it leaves your bat is equal to the speed of your bat times the weight of the bat times the speed of the ball times the weight of the ball, with a few other factors (gravity, friction, the "springiness" of the bat and ball)...

Third Law - for every action there is an equal and opposite reaction.

Blow up a balloon. Keep the neck pinched closed. Now release the neck. The balloon flies away as the air is forced out the neck - air goes one way, balloon goes the other.

Answer 3

All mass or matter in our universe is an example of Newton's 3 laws of motion.

All masses maintain constant velocities unless acted on by net forces greater than zero.

All masses accelerate when acted on by net forces greater than zero.

All forces on all masses generate equal and opposite forces.

So, to answer your question, just list all tangible things (mass or matter) you can think of. Your Aunt Harriet, with her massive whatever, follows Newton's three laws. Your book on the shelf is abiding by all three laws by just lying there. But you get the picture, you don't need someone to make up a limited list, you can do that yourself.

Answer 4

Actually they four of them:
III.Action and reaction:If you want to get rid of something you realize that it sticks to you.
I.Inertia: everything sticks you until you will get rid of them.
IV. Superposition: almost all the time there are more than one person who want to get rid of the same thing at the same time.
II.Force and acceleration: let the force be with you to increase your speed, because more massive is something the more force you will need.
