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.
A screw has threads that create more surface area contact with the wood compared to a nail, distributing the force over a larger area. This design helps to reduce the force required to drive a screw into wood compared to driving a nail.
A screw is a simple machine that allows for the transfer of force over a longer distance, making it easier to apply a greater force with less effort. By twisting the screw, the rotational motion is converted into linear motion, enabling it to move objects with less force compared to lifting or pushing directly.
Radial forces.
Friction force
Two forces that can make an object move are external forces, such as pushing or pulling it, and gravitational forces acting on the object.
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
You have to move it (by your hand) and it takes some force to do that...
The lighter the vehicle the less energy it takes to move it.
Radial forces.
Tectonic forces.
the threads determine the depth the screw should move
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
Generally, yes. The atoms in a substance move around much less the cooler they are, so the substance takes up less space.
A balanced force acting on an object at rest does not cause any motion because the forces cancel each other out. On the other hand, an unbalanced force on an object at rest will cause the object to start moving in the direction of the greater force.
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.
Other planets have more or less gravity than Earth, so the energy needed to move things around is also more or less.
Balanced forces are forces of equal magnitude and opposite direction that cancel each other out, resulting in no change in an object's motion. Unbalanced forces are forces that do not cancel each other out, causing a change in an object's motion by either speeding it up, slowing it down, or changing its direction.
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
