What is the action of sitting on the chair?
When sitting on a chair, the action force is your weight that pushes down the chair. The reaction force is the opposite force from the chair, which is equal to your weight. This force pushes your body upward.
What force is pushing up when you sit in a chair?
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.
How does Newton’s third law apply to a chair?
It is the contact force of the person on the chair and the contact force of the chair on the person. (This is the pair of equal and opposite forces.) Newton’s 3rd law applies perfectly. You are making the mistake of assuming the persons contact force with the chair equals their weight. It does not.
What does Newton’s first law of motion say?
The two forces together are called an interaction pair. are sitting still on a chair. Your weight is a force pushing down on the chair . It is not obvious that there is an against you. Newton ‘ s First Law says that there on a stationary object ( yourself) must be balanced. accelerate downwards in the direction of the resultant force.
Which is an example of Newton’s third law?
These forces are called action and reaction forces. The two forces together are called an interaction pair. One example of Newton’s third law is when you are sitting still on a chair. Your weight is a force pushing down on the chair. It is not obvious that there is an equal opposing force from the chair, pushing upwards against you.
What happens if the force on a chair is not equal?
If the force of your weight on the chair did not have an equal opposing force, then the forces on you would be unbalanced and you would accelerate downwards in the direction of the resultant force.
