Principle behind how a screw does it's work?
It holds things together like wood, while a nail would not work as good as a screw because, a nail might fall out.
What does a screw do to the force you apply?
How much force is needed to push a screw/nail into the wood is a function of the size of the surface area of the part of the screw/nail that you are trying to put in. This idea is described in the pressure function which says P=F/A The wood has a certain resistivity to deform but with enough Force (applied with a hammer/screwdriver) over a small enough Area (the bottom of the screw/nail) the Pressure will be enough to drive it through. your mom
Why does a Screw takes less forces to move into wood than a nail?
a screw possesses both rotational kinetic energy and translational kinetic energy while a nail possesses only translational kinetic energy as it moves through the piece of wood hence the screw moves faster since its motion is backed by more energy than the nail.
To fix 2 pieces of wood a screw is better than a nail why?
because with a screw you have much more area gripping the wood and cannot under normal circumstances pull it out without shredding the wood where a nail has much less area in contact with the wood and being held in by friction only can be simply pulled out without tearing or shredding the wood.
Why is overcoming a resistance force using a screw so easy?
The inclined plane pulls the screw into the wood.
Why is it easier to insert a screw into wood than to insert a nail?
A screw holds wood together better than a nail because the threading of a screw provides a horizontal grip on the wood. Nails are driven down into wood and have nothing but the pressure of the wood to keep them attached, which means it is easier to pull a nail straight out of a board than a screw.

Why does a screw work better for wood?
Screws are a more secure fastening than nails because the only barrier to removing a nail is the friction of the sides of the nail against the wood, so it can be pulled loose by a simple torsion force. A screw, however, has threads, so a torsion force cannot remove a screw without destroying part of the wood in the process.
What hold two pieces of wood together better a screw or a nail?
A screw has an irregular shape, and has more to stop it from falling out. Also, A screw has an advantage because it's drilled in and the spirals makes it stick in faster and doesn't take long as a nail to hammer it.So, it takes a few seconds to screw the screw in.
Is nail a screw?
no. to insert a nail into say... a piece of wood, youd use a hammmer. to insert a screw into a piece of wood, youd a screwdriver, wrench, etc.
Can you hammer a screw?
It is not a good practice, but people do it. Some will tap a screw with a hammer to start a hole. Others will drive it all the way in. That is bad for the screw and the wood.Hammering a screw is counter-productive and will not have good results:When you hammer a nail into wood, the sides of the nail compress the wood. The compressed wood wants to expand pressing on the sides of the nail. The pressure keeps the nail in place preventing it from coming out of the wood.When you hammer a screw into wood, the threads of the screw "chew out" the wood pressing it downward, possibly compressing it in a downward direction, leaving little or no wood to hold the screw in place The compressed wood, wanting to expand may tend to expand upwards pushing the screw out.
Can you please tell me the step to step process on which holds better wood a nail or screw?
don't know what you mean by step by step process, but I can say with confidence that a screw will almost always hold better.
Why is it easier to pull out a nail but not a screw from wood?
The thread pattern of the screw anchors it in the wood. You not only have to pull against frictio, but also against the natural strength of the fibre and wood itself.

Why is a nail able to pierce wood?
Because... When you hit the head of the nail, the force you exert is concentrated right at the point - forcing it into the wood.

a screw possesses both rotational kinetic energy and translational kinetic energy while a nail possesses only translational kinetic energy as it moves through the piece of wood hence the screw moves faster since its motion is backed by more energy than the nail.
What will hold two boards together better - a nail or a screw?
A screw holds wood together better than any nail because it resists being pulled out much better. A screw is also easier to remove without damage. However, screws are more expensive to make and take longer to put in, so nails are still used in a lot of timber work.
