The Force That The Floor Exerts On You Is

True when you jump you accelerate upward because the floor exerts an upward force on you.

The force that the floor exerts on you is.

Similarly a car accelerates because the ground pushes forward on the drive wheels in reaction to the drive wheels pushing backward on the ground. Equals your change in momentum the floor has to exert the same impulse on you no matter how you land. In order to walk on a floor or any other surface your foot must push backward on the floor action force so that the floor pushes you forward reaction force. Your weight caused by gravity is pulling you down the floor is reacting by pushing back.

Newton s third law states that every action has an equal and oposite reaction you may not think this but when you re standing ont he floor you are excerting a force against the floor. And it goes same for the fourth case. Newton s first law states that if all the forces cancel each other out. This physics video tutorial explains how to find the normal force on a scale in a typical elevator problem.

The floor exerts a reaction force forward on the professor that causes her to accelerate forward. We call this force the reaction force. Therefore the baby does not plummet down the earth. It discusses how to calculate the apparent weight.

The force that your foot and the floor exert on each other is a friction force between the sole of your shoe and the floor. In the vertical direction the net force is zero since the velocity component in that direction must remain zero. The actual normal force comes from the floor of the elevator exerting the same force as the baby s weight force which follows newton s third law. But since impulse equals force times time you can decrease the force that the floor exerts on you by increasing the stopping.
