This was proposed by Sir Issac Newton over two hundred years ago. It is known as Newton's Third Law of Motion. It relates to forces and how things move and yes, it does appear to be true. Let's see how it works.

If you go out for a walk, you push down on the sidewalk and the sidewalk pushes back on you, thus the force down (gravity) and the force up (from the sidewalk) are balanced and you neither go down nor go up. This is also happening for your forward motion as well. Your legs and feet push back on the sidewalk and the sidewalk pushes on you to push you forward.

Now you come to an icy patch on the sidewalk. You still push back, but the sidewalk (covered in slippery ice) can not push back on you with the same force. This has a few results; because the force pushing you forward has reduced, you do not go as fast. Second, and this relates to Newton's Second Law of Motion, when your feet slip on the ice, you are pushing a much smaller mass (just your legs, not the mass of your entire body), so your legs speed up. If you were not ready for this change in leg speed, your legs will probably no longer be under you. We once again have an unbalanced force as the air under you can not support anywhere as much weight as your legs and gravity's force is effectively unopposed; you fall. Even in this action your action (you falling to the Earth) has an equal and opposite reaction (the Earth moving towards you). Because the Earth's mass is so much larger than your mass, the Earth's movement will be quite small, while yours will be much larger, getting you to the ground.

Here is an example that is not all wet. If you are standing on a boat and try to jump out into the water, you push against the boat. The boat pushes back on you and you go jump in the lake. In the meantime, the boat has taken the force you applied to it and is now drifting across the lake. Think of what is happening as you now turn around and swim to catch your boat. What are you pushing against and how? What is pushing you trough the water?

How do all of Newton's laws apply to the performance of my mousetrap car?

Newton's first law says that, "an object at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." The mousetrap car relates to this because the car doesn't move until the force of the mousetrap moves it and then it doesn't stop until it hits something or until all the kinetic energy is changed into another type of energy, like friction or heat. Newton's second law says that, "the acceleration is directly proportional to the force and inversely proportional to mass." This means that the smaller the mass is, the faster the acceleration is. Newton's third law says that, "for every action, there is an equal and opposite reaction." When the car is rolling it has the reaction of moving forward, but friction is acting upon it in the opposite direction. Eventually the force of friction will even out, displaying that for every action there is an equal but opposite reaction.

What is an action force?

Action Force is a force that exerts a force on another object. It often comes in pairs with the Reaction Force, forming an action-reaction pairs. The action-reaction force is Newton's third law of motion.Newton's third law of motion states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.what they said

For every action there is an equal and opposite reaction True or false?

The first part of Newton's third law of motion is:"Actioni contrariam semper et æqualem esse reactionem: ..."Translation:'To the action there is always opposed and equal reaction: ...'This is often expressed as:"To (or For) every action there is always an equal and opposite reaction: ..."Therefore the phrase in the question is not right because Newton's law has been incorrectly quoted. The word 'always' should also have been included.However, given that the quoted phrase is only half of what Newton actually stated as his third law, then, in the field of motion physics, it can only be HALF RIGHT at most.And even if Newton's law had been correctly quoted, it is still only a law of motion physics, so it is not necessarily 'right' in the sense of a being a universal truism.

No, it's a force. Gravity just keeps you from floating around. For a reaction there is always an equal and opposite reaction. Newton said that. Look up Newton's Laws of Physics (or motion).

How does Newton's Third law apply to bottle rockets?

The rocket's propellant shoots out of one of its ends. Newton said that every action (like rocket propellant shooting out) is accompanied by an equal (same force) but opposite re-action. So, if the propellant shoots out with a force of, say, 1,000 pounds, then the rocket is pushed in the opposite direction (forward, we hope) by 1,000 pounds. It works! Try standing on one tiptoe while holding a weight of 5 or 10 pounds out to your side. Move the weight quickly sideways across your body and you will find your body moving (twisting because of that toe on the floor) in the opposite direction.
