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.

What forces move it in and out?
Radial forces.
When several forces act on an object and the object does not move can the forces be balanced?
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
Compare how balanced and unbalanced forces affect an object at rest?
balanced forces don't move an object, but unbalanced forces on an object do move
What are unbalance forces?
When there is more force acting on one side of an object than the other side. Therefore the object will move to the side with less force.
Which would take less force to move a heavy object or a light weight object?
When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.
How does screwdriver use the principles of forces?
You have to move it (by your hand) and it takes some force to do that...
Why is it important that a solar car should be lightweight?
The lighter the vehicle the less energy it takes to move it.
What forces move it in and out?
Radial forces.
What forces move the continents?
Tectonic forces.
How does the number of threads on a screw affect the distance the screw moves?
the threads determine the depth the screw should move
When several forces act on an object and the object does not move can the forces be balanced?
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
When meterials are cooled they get smaller?
Generally, yes. The atoms in a substance move around much less the cooler they are, so the substance takes up less space.
Compare how balanced and unbalanced forces affect an object at rest?
balanced forces don't move an object, but unbalanced forces on an object do move
What is a screw thread mechanism?
Picture a nut on a screw. You are holding the nut so it can't turn, but allow it to go up and down the screw. The screw is restrained so it can turn, but not move back and forth. As you turn the screw one way and the other, the nut will move up and down the screw. That is a trivial example of one very common screw thread mechanism.
When you go on different planets it takes more energy to move something than it is on Earth Is it more gravity or less gravity?
Other planets have more or less gravity than Earth, so the energy needed to move things around is also more or less.
Definition for balanced and unbalanced forces?
Balanced forces are forces that are balanced, so the object won't move. O will represent this. The forces, ---------->O<----------, are the same, so the object won't move. For unbalanced forces, ---------->O<--------------------, The force on the right is stronger, so it will move to the left.
How gases expand?
As heat is put into a gas, the molecules gain energy and move faster and faster (the temperature goes up). The faster they move the less the intermolecular forces become so the further they can move away from each other
