What is Newton’s third law of motion? Part 1
WHAT IS NEWTON’S THIRD LAW?

Newton’s third Law of Motion States that for every action there is an equal and opposite reaction. This Means that when you act there will always be a reaction for what you have acted upon. Here are a few examples, if you are in a canoe, which is a light object, and you throw a heavy bowling ball into the water straight in front of you, you will most likely move backwards therefore being an action and reaction. Also when you have a balloon full of air, and you let it go (the action) it will move in the opposite direction that the air inside of it is coming out (the reaction). So for every up there is a down, for every push there is a pull.

Newton had a second law as well. This is, if a force is applied to an object it will accelerate in speed. So when there is a greater force, the greater the acceleration will be. This means that when a force is put on an object, the object will move faster immediately, and when you put
of a force onto that object it will move even faster immediately. For instance if you are at a bowling alley and you kick a bowling ball it will not move as fast a soccer ball on a soccer field even though the soccer ball has to avoid more friction because the soccer field would be more rough then a bowling alley floor. The reason being that a bowling ball has more mass then a soccer ball so it would be harder for a person to kick the ball with more mass, but when the bowling ball is rolling down a hill it would go faster than a soccer ball rolling down a hill because of its mass again. The bowling ball contains more momentum which makes it go faster when on slanted ground.

Newton’s first law of motion states that objectsrest will remain at rest while objects at motion will remain in motion till another force acts upon it. This law means that if an object is not moving it will stay not moving until another object or force makes it move. So for an example, if a tennis ball is kicked on a rough tennis court it will keep rolling until a force like friction stops it. Or if a person is riding in a Car and that car jolts to a stop, you will keep moving forward in till something that is in front of you, like an air bag or a seat, stops you from moving any longer.
Accelerate= To accelerate is to move faster
Force= Cause of motion or change
Friction=The force that resists relative motion either between bodies or other objects.
Mass=A quantity of aggregate of matter usually a considerable size.
Momentum= A property of a moving body/object that the body/object has by virtue of its mass and motion and that is equal to the product of the body/objects mass and velocity

So in conclusion the third law of Isaac Newton is for every action there will always be an equal and opposite reaction.
