# Is easier to open a door by holding it from its edge?

## Where should you push on a door so that it is easiest to open?

As distance increases, torque increases and so the rotational effect increases. Hence, it is easier to push open a door by holding the knob than by pushing closer to the hinge. To explain it to a child, just explain that it’s easier for a force to work when it has some more “space” to move about than, when it doesn’t.

## Is it easier to open the door if the handle is far from the hinges or close to the hinges?

Why is it easier to open a door closer to the handle than the hinge? It is easier to open a door by pushing near the knob than closer to the hinge because the farther away from the fulcrum (hinge) you push, the less force that needs to be applied. It is a second class lever because the fulcrum is closer inward.

## Why is it easier to push a door away from the hinges?

As the applied force moves away from the hinge, the process I described in the above paragraph kicks in. The more of the door is on the same side of the force as the hinge, the more inertia that side produces and the slower it accelerates. Again, because the hinge can’t move, it provides an opposing force.

## Why we prefer to open a door about its corner rather than pushing in its middle?

Answer:It’s simple. You apply same force in each case but torque is different. Torque acting on the hinge is more if the point of force applied is farther from hinge. … And larger is the perpendicular distance from the axis of rotation, less is the force needed to move it.

## Why can’t you open a door by pushing on its hinged side?

Why can’t you open a door by pushing on its hinged side? A force exerted at the hinges produces no torque about them. It’s must easier to carry a weight in your hand when your arm is at your side than it is when your arm is pointing straight out in front of you. Use the concept of torque to explain this effect.

## Why it is easier to open a door if you pull perpendicularly to the door instead of pulling at an angle?

The reason is because of torque which basically creates a rotational effect. … As distance increases, torque increases and so the rotational effect increases. Hence, it is easier to push open a door by holding the knob than by pushing closer to the hinge.

## Why don’t we put door handles in the center of the door physics?

Explanation: if we put the the door handles in the center of the door then we need to large force and also our force get separate. If we decrease the distance between handle and door fixed point then we need large force to pull or push it.

## Why are doorknobs placed at the edge of the door farthest from the hinge?

Most doors open by rotating on a hinge. As such, they are opened through the application of torque. To make it as easy as possible to open the door, the knobs are placed as far from the hinge as is feasible. This maximizes the lever arm, reducing the amount of force needed to open the door.

## Why is it easier to open a door with the doorknob?

It is easier to open a door by applying the force at the free end of it because of the larger the perpendicular distance, less is the force needed to turn the body.

## Is it easier to push or pull a door?

When pulling a door, the same forces apply, except force is applied to the knob and pulled onto the knob which then applies force to the door. … Thus due to the loss of momentum, pushing a door seems easier than pulling a door, but if one were to push a door without momentum, it would be almost as easy.

## Why is it easier to open a door by applying the force at the free end of it?

(iv) It is easier to open the door by applying force at its free end because the increased perpendicular distance decreases the amount of force required to open the door as the moment of force is the product of force and the perpendicular distance.

## When you open a door is any work done?

ANSWEROpening a door requires our hand to apply force by pushing and pulling which is a contact force. There is some frictional force in the door hinge, against that we apply force. The hinge friction is again a contact force.

## Is the force created when an object is physically push or pull?

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.

## Will a door open if a force is applied on its hinges?

To open or close a door, we apply a force normal to the door. … If the force is applied at the hinges the perpendicular distance of force is zero. Hence, there will be no turning effect however large force is applied.
