A person would sit on a chair without falling threw by having a seat on it and if there isn't too much weight on it.
The action force when you sit down on a chair is the force exerted by you on the chair. This force is equal in magnitude and opposite in direction to the reaction force exerted by the chair on you, which supports your weight and keeps you from falling through the chair.
Be constapaited
You don't fall out of your chair when you sit down because of gravity. When you sit, your weight creates a force that is balanced by the supporting force from the chair. This balance of forces keeps you in place and prevents you from falling.
The upward force exerted by a chair when you sit on it depends on your weight and the design of the chair. The force is equal to the force of gravity acting on you, to keep you balanced and prevent you from falling.
When you sit in a chair, the action force is the downward force you exert on the chair due to your weight. The reaction force is the upward force exerted by the chair on you, supporting your weight and keeping you from falling to the ground.
No, a 3-month-old should not sit in a high chair as they do not have the necessary neck and core strength to sit upright and may be at risk of falling or injury. It is recommended to wait until the baby is able to sit up independently before using a high chair.
When you sit in a chair, the force exerted toward you is the normal force, which is equal in magnitude and opposite in direction to your weight. This force is what keeps you from falling through the chair due to gravity.
If your feet are off of the floor, then the chair exerts your total weight against you.
WHEN I SIT ON A CHAIR IT MAKES ME RELAX.
This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When you sit on a chair, your body exerts a downward force on the chair, and in response, the chair exerts an upward force on your body to support your weight and keep you from falling.
Babies can safely sit in a high chair when they are able to sit up on their own without support, usually around 6 months of age.
