What action and reaction forces are presented when you are sitting on a chair?
Your weight exerts a downward force, while the chair exerts an upward force equal in magnitude to your weight.
Do all action-reaction forces produce motion?
Some do and some don't. In the case of someone sitting on a chair, they exert a downward force on the chair due to their weight. The chair exerts an equal and opposite reaction force on them but, since this upward force acting on the person is equal to their weight, the net force is zero and the person does not accelerate. However, consider now if the person pushed themselves up off the chair with their hands. They are now exerting an additional force on the chair with their arms along with the force due to their weight. The chair will exert a reaction force on the person that is equal and opposite to the combined downward force due to the person's weight and their arms pushing. Since it is equal to the weight plus the pushing force of the arms, it will be greater than the downward force on the person due to their weight and a net upward force will be produced, accelerating the person upwards.
When you sit on a chair a resultant force on you is?
The Answer is (A) - Zero Explanation: When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces.
What does force equal in science?
Your weight is a force. More specifically the force that keeps you from falling to the center of the Earth at this very moment! It is sometimes confused with mass because weight is often displayed in units of mass (i.e. the kilogram). Mass however does not change when you visit other planets, nor does it become zero in free fall as weight does. But, a force is not equal to weight because a force is a more general thing. In particular there are four fundamental forces in our Universe: gravity, electromagnetism and the strong and weak nuclear forces. Note that it is often the electromagnetic force that provides your weight; it is the electric repulsion between atoms that keeps you from falling into the floor!
What is the weight in newtons if a chair's mass is 90 Kg?
Weight = (mass) x (acceleration due to gravity)= 90kg x 9.8ms-2= 882N
What force is acting when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
Why does a chair not collapse when you sit on it?
The chair is pushing up with a force equal to your weight.

When you sit in a chair what exerts against you?
Assuming that the seat of the chair is horizontal, and you an penis d the chair are stationary, the key forces here are your weight, which is acting vertically downwards on to the chair, and an equal reaction force, or normal contact force, of the chair acting on you. This force acts vertically upwards. You could also include the forces of the air acting on you and vice versa, but this is probably not what you're after.
How come equal action reaction forces doesnt cancel?
Excuse me ... they DO ! That's why, when you sit in a chair and the downward force of your weight against the chair and the upward force of the chair against your bottom exactly cancel, your bottom doesn't go accelerating somewhere.

How does math apply to making a chair?
Measuring all legs and arms to make sure they are of equal lengths, unless you want a wobbly chair. :)
When you sit in a chair what force does it exert against you?
A force exactly equal to the weight of your posterior against the chair. You know positively that the forces there must exactly cancel and add to zero, otherwise a net, non-zero force would be present, and your butt would accelerate.
Does a chair have the same temperature equal to greater than or less that the temperature of the air?
The answer will depend on where the chair is, the material it is made of. A black metal chair, out in the sunshine will be hotter than the surrounding air. The same chair, indoors, will probably be the same temperature. Also, metal chairs will feel colder than textile covered chairs.
What is a real life example of Newtons third law?
A real-life example of Newton's third law is when you sit on a chair. As you sit down, you apply a force on the chair, and the chair applies an equal and opposite force on you. This is why you don't fall through the chair but instead remain seated.
What are some examples of Newton's third law of motion?
Newton's third law of motion states that for any action, there will be either an equal or opposite reaction. Cause and effect would be a great example of this, as does conservation of momentum and energy.When you sit down in your chair, not only does the weight of your body push down on the chair, the chair also pushes back up on your body, keeping you What_are_examples_of_Newton's_Third_law_of_Motionfrom falling to the floor. You pushing down with your weight, while the chair pushing up with its material, is an example of newton's third law of motion.
