Who said With every reaction there is an equal and opposite reaction?

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?

∙ 11y agoWhy such a simple question? Newton's THIRD law states:
For every action there is an equal but opposite reaction.

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 can be said about the reaction?
What reaction to what? You didn't specify.
The opposite of said is?

Structural Demolition tell me about this thundercontracting for my house services?
if it is equal to zero the chemical reaction is said to be at equilibrium
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
Who said for every action there is a reaction?
Sir Isaac Newton said that for every action there is an equal and opposite reaction.
What is the mathematical description of collision?
Sir Isaac Newton said it best. For every action there is an equal and opposite reaction. You hit something, both objects react opposite but equally with respect to their size and weight.
In Science what is the act of moving?
Energy of Movement or force=DAnd walking,running,jogging,skipping and kicking!!As Newton Said, "With every action there is an equal and opposite reaction"
Equal but opposite forces are said to result in an?
NET force
Does gravity make a person jolt forward when a car stops's?
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).
When a chemical reaction and it's reverse occur at the same time and rate the reaction is said to be?
When the reaction reaches a point where reactants produced is equal to products produced the reaction is said to be in equilibrium. If that is what you afre talking about
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.
What must forces in each direction be doing to be in equilibrum?
As Newton said, they must be equal and opposite and collinear.
Why is the speed of a recoiling gun less than the speed of the fired bullet?
Newton said "For every action, there is an equal and opposite reaction." The action is pushing the bullet in one direction. Reaction is the gun being pushed in the other. The energy is speed times mass. The gun masses much more than the bullet, and so will move proportionately slower than the bullet. Which is a very good thing- or the recoil of the gun would kill the shooter.
What is meant by recoil in a gun?
recoil is the backward momentum of a gun when it is discharged.Remember that, for every action, there is an equal and opposite reaction. So, you have a force blasting forwards, and it's going to push back in the opposite direction. That's recoil.Recoil is the force exerted on the operator of a firearm as a result of the firearm's operation.The Laws of physics dictate equal and opposite forces for a reaction. The same force which accelerates the bullet creates an accelerative force on your body when you shoot. While you have the weight of the firearm plus your own body, and thus experience very little movement; the far lower mass (and corresponding resistance to acceleration) of the bullet results in said bullet gaining a great deal of speed and departing the barrel of the gun.
Are unbalanced forces equal in size and opposite in direction?
Two forces equal in size and opposite in direction are balanced, not unbalanced, because they cancel each other out. Any set of forces which has a resultant of zero is said to be balanced.
What opposite of said?
The opposite of said is ask or request.
