Standing On The Floor Action Reaction

When you stand on a hard stone floor the floor deforms very slightly under your weight.

Standing on the floor action reaction. Downward pressure of the person acting on floor this latter one is called weight. Sometimes it is rather tricky to identify an action reaction pair. Consider a person standing on the surface of the earth fig. F n is the normal force.

The space shuttle engines push out hot gases action force and the hot gases put a force on the shuttle engines reaction force so the shuttle lifts there is no sling shot doing it when the ball that was thrown hits the floor the floor has an equal and opposite reaction forcing the ball up and into the man s face. The term normal means anything at a right angle in math or the sciences. Pull of gravity of the person acting on earth. The reaction force of the floor acting on the player can be decomposed into vertical and horizontal components v and h.

The weight of the person is the gravitational force exerted on him by the earth. Newton s first law states that if all the forces cancel each other out. People action reaction pairs in this case. The person exerts an equal but opposite gravitational force on the.

Have equal magnitudes and form an action reaction pair b. Between this vertical component of the reaction force and the weight of the player the resultant force in the vertical direction is zero in average when the player is allowed to jump while running. These two forces a. We call this force the reaction force.

If you are standing on the floor motionless what are the forces that act on you. Have unequal magnitudes and do not form an action. Pull of gravity of earth acting on the person and. Have equal magnitudes and do not form an action reaction pair.

Have equal magnitudes and form an action reaction pair. The 3rd law the law of action reaction. When you stand on the floor the force of your body pushing down on the floor is a matched by the floor pushing up on your body b less than the reaction force applied by the floor c a reaction to the floor pushing up. Acts on two different objects point in opposite directions and equal magnitude act as pair or not at all faonb fbona.

Standing on the ground you push on the ground with a force due to gravity f g down and the ground pushes back on you f n up. When an action force occurs the reaction force is always a in the same direction as the action force b. Have unequal magnitudes and form an action reaction pair d. 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. Upward support of floor acting on the person and. The downward pull of gravity and the upward normal force of the floor. A person standing on a horizontal floor is acted upon by two forces.

An action reaction pair of forces.
