How much force does a floor exert on you?
The force a floor exerts on you is equal and opposite to your weight. This force is known as the normal force, which supports your weight and prevents you from falling through the floor. The magnitude of this force depends on your mass and the acceleration due to gravity.
How much does 1 million pounds of steel weigh in water?
ANS1:Because of the natural buoyancy water provides steel actually weighs less in water. so 1 million pounds of steel in water would weigh only 500,000 pounds. Cheers!! ANS2:Bull. Answer 1 is a soup sandwich. The earth is still pulling the steel towards it with the same force. That force is its weight. That the water is also being pulled toward the earth and causes the buoyant upward force on the steel does not make the steel's weight less. That is like arguing that a hunk of steel is weightless because the floor is pushing against it as hard as it is pushing against the floor or arguing that a steel-hulled ocean liner has no weight because it floats in water. The steel will still have the weight of 1 million pounds-force.Since the specific gravity of steel is 7.8, the upward buoyant force will be 1/7.8 of its weight. If you insist on using pounds to measure weight, the upward buoyant force would be 128,000 pounds-force. You could subtract this from the 1 million pounds-force of the steel to get 872,000 pounds-force. You could call this its effective weight or net downward force if you want to make the point that that force is what is pressing on the bottom of the body of water.This is probably the answer you should put on your homework if you are a student in a U.S. public school. If you put anything else down, you will likely confuse your teacher especially if you try to argue the difference between pound-force, pound-mass poundals, and slugs.ANS3ALOT!

When a person pushes a crate across the floor what force is working in reaction to the pushing force?
The force that resists the motion of the crate is the force of friction between the crate and the floor. This frictional force acts in the opposite direction to the pushing force applied by the person, making it harder to move the crate.
How much force will be required to lift a weight if it weighs 300 pounds?
If the weight is 300 pounds, you will need to apply a force of at least 300 pounds to lift it against the force of gravity. This force is known as the weight of the object.
What causes an object you are pushing across the floor to stop when you stop?
The main reason an object stops when you stop pushing it across the floor is due to the force of friction between the object and the floor. When you push the object, the force you apply overcomes friction and moves the object forward. When you stop pushing, friction between the object and the floor slows it down and eventually brings it to a stop.
If a person weighs 150 pounds and is standing on the floor and the floor is not moving what is the force that the floor exerts on the person?
150 lbs. In order for the floor to support you it must resist an equal force.
Does a sunken ship sitting on the ocean floor have a buoyant force on it?
Yes, a sunken ship on the ocean floor experiences a buoyant force pushing up on it that is equal to the weight of the water displaced by the ship. This buoyant force helps to keep the ship in place on the ocean floor despite its weight.

The force a floor exerts on you is equal and opposite to your weight. This force is known as the normal force, which supports your weight and prevents you from falling through the floor. The magnitude of this force depends on your mass and the acceleration due to gravity.
To stop a table in your classroom falling through the floor what must the floor do against the force of gravity pulling the table down?
Newton's third law of motion states that: "For applied force (A), exists some force (B) of equal magnitude acting in the opposite direction of the force applied.". The force of the weight (which is the mass of the table multiplied by gravity) [W=mg] pushing down on the floor is counterbalanced by an equal and opposite force of the floor pushing up on the table. This is why the table does not fall through the floor. The floor is able to provide this force without allowing the table to move through it because the bonds between its atoms are strong enough.

What are the two forces acting on a person as they move up and down in an elevator and when are these two forces equal and when are they not equal?
When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.
What causes an object you are pushing across the floor to stop when you stop?
The main reason an object stops when you stop pushing it across the floor is due to the force of friction between the object and the floor. When you push the object, the force you apply overcomes friction and moves the object forward. When you stop pushing, friction between the object and the floor slows it down and eventually brings it to a stop.
What is the force of pushing on a surface divided by the area of that surface?
This is usually expressed as weight or force per square area. In imperial measure (USA) pounds per square inch In Metric KG/meter2
What horizontal force P is required to drag a sack of rice weighing 110 pounds. in a horizontal floor if the coefficient of friction between the floor on the sack of rice is 0.25?
The force of friction acting on the sack of rice is the product of the coefficient of friction and the normal force, which in this case is the weight of the sack (110 pounds). Therefore, the force of friction is 0.25 * 110 = 27.5 pounds. The horizontal force required to overcome this friction and drag the sack of rice is equal to the force of friction, so a force of 27.5 pounds (P = 27.5 pounds) is required.
How does the act of walking involve pushing on the floor to the left and the floor itself?
When walking, you push against the floor with your feet to propel yourself forward. This pushing action creates a reaction force from the floor that helps you move in the desired direction.
