When you stand on a floor does the floor exert an upward force against your feet?
Yes
When you standing on the floor does the floor exert an upward force against your feet How much force does it exert?
Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.
When you sit in a chair what is exerted against you?
If your feet are off of the floor, then the chair exerts your total weight against you.
Why do you slide on a slippery floor?
There may not be enough friction between your feet and the floor. You need friction to be able to exert a force against the floor, to balance yourself and move in the direction you desire.
How do you determine square foot?
Example: Measure a floor-- it is 20 feet long and 30 feet wide 20 x 30 = 600 square feet.
Why is it difficult to walk on a slippery floor?
There may not be enough friction between your feet and the floor. You need friction to be able to exert a force against the floor, to balance yourself and move in the direction you desire.
When standing on the floor does the floor exert an apward force against your fit how much force does exert why you are not move forward by the floor?
Yes, the force exerted by the floor on our feet is equal to the force that our feet exerted on the floor, or it just depends on your weight, If you are heavier than the normal. When you stand, the longer the time you stand, the more pain you feel on your feet. And we can't be move upward by the force that the floor exerted on our feet because of the force of our weight that keeps us on the ground, and also because of gravity.
There are 2 forces acting on Gary the goat one force is his weight and the other is the rock pushing against his feet What is force A and what is force B?
gravity
How friction is useful in pushing a car?
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
Does the floor exert an upward force against your feet?
no gravity prett much does the trick, forcing you down to the floor and since I never saw a floor float up when a load was taken off, I will stick with no & gravity
How does pressure change with depth why?
The pressure on an object increases with depth because there is more pushing on it. For example, four feet below the surface of water, there is a layer of water four feet thick pushing on the object and the water around it. Now several miles down, this layer of water is much thicker, and so exerts more pressure when it is pushing down. In this example I used water, but the same can be applied to any fluid, including air.
The perimeter of a square floor is 144 feet what is the area of the floor?
The floor's area is: 1,296 square feet.
