When you open a door, you exert a force in the direction of the door's motion. This force creates torque, which causes the door to rotate around its hinges. Work is done when this force causes the door to move against resistance, such as friction between the door and the door frame.

What happens when a person pushes on a stuck door?
When a person pushes on a stuck door, they exert a force that can potentially overcome the resistance holding the door shut. Depending on the severity of the obstruction, additional force may be required to open the door. It is important to be cautious when pushing on a stuck door to avoid injury.
Two examples of objects on which you exert forces when you are doing your schoolwork?
downward force of your body on the chair force on pen to write with
What is an example of pulling force?
An example of a pulling force is when you tug on a door to open it. As you pull the door towards you, you are exerting a pulling force on the door to overcome its resistance and open it.
When you pull a door open if the force the door exerts on you is equal to the force you exert on the door why dont you move?
-- The door's force on your hand is not necessarily equal to the force of your hand on the door. If it were, then the sum of the forces at the hand-door interface would be zero, and there would be no acceleration there to open the door. The point where the action and reaction are equal is the point in your arm where the muscle is anchored to the bone. Or better yet, between your feet and the floor. -- You weigh more than the door weighs. So equal forces on you and on the door produce more acceleration and more speed of the door than of you. (For the same reason that the rifle recoils at a slower speed than the bullet's muzzle velocity.) -- If you were on hinges, or on ice skates, then you would move too. The door's mounting arrangement is built in such a way that it's more free to move than you are, when your feet are planted and you're using your legs to keep you upright.
How would the force needed to open a door change if you put the handle in the middle of the door?
If the doorknob were moved to the middle of the door, it would take twice as much force to open it than if it were at the edge of the door. With the mass of the door being equal. Moment = the force to open the door times the distance to the center of the hinges. If the distance were cut in half it would take twice the force to keep the equation true.

Why is easier to open a door by applying the force at the free end?
Applying force at the free end of a door increases the distance from the hinge, creating a greater torque which helps overcome the resistance of the door's weight. This leverage amplifies the force applied, making it easier to open the door with less effort.
In order to pull a door open you must apply a what?

What kind of force does it take to pull a fridge door?
It typically takes about 10-15 pounds of force to open a refrigerator door, but this can vary depending on the design and condition of the door's hinges and seal. The force required is usually within an average person's capability to open comfortably.
How much force is exerted on a door handle?
The force exerted on a door handle depends on the weight of the door, the distance from the handle to the hinge, and how much force is applied to open or close the door. It can range from a few pounds to several tens of pounds.
Why are door handles placed towards the corner of the door?
The door-handle is usually on the opposite side of the door from the hinges to give the best leverage on the door, ie you need less force to pull the door open. You are producing a torque on the door. (Torque is a rotational force). Essentially, as you apply a force to rotate something, less is needed to cause rotation if you apply that force further away from the center of the rotation (in this case, the hinges). Try to push open a door by pushing on the door very close to the hinges, and you will find that it is quite difficult.
What friction is used while opening a door?
While opening the door you do work to generate a moment of inertia that opens the door. The moment of inertia= force applied x perpendicular distance between the point of application of force and the axis of rotation. The greater the perpendicular distance the easier it is for you to open the door, i.e. a less amount of force can be applied to open the door. I hope this was useful.
What is a sentence for push?
force is push and pull
