Which would drive a nail deeper into a piece of wood a heavy hammer or a light hammer?

The heavy hammer would drive the nail further than the light hammer because of Law # 2, F = ma. The heavy hammer has more mass and therefore more force against the nail than the light hammer.

Why is it possible to drive a nail into a piece of wood with a hammer but it is not possible to push a nail in by hand?

The nail can penetrate the wood because it is sharp, applying high pressure to the surface area it contacts. The nail’s head is relatively much wider, so it will not penetrate your hand as easily as the sharp end, but it is clearly not engineered to be pushed in by hand.

Why isn’t this girl hurt when the nail is driven into the block of wood?

Why isn’t the girl hurt when the nail is driven into the block of wood? The wooden block’s tendency to remain at rest prevents it from sudden motion downward against her head.

What drives a nail into the wood when struck by a hammer?

On lifting the Hammer, its potential energy is stored in the hammer on striking the nail with a hammer this energy is used in driving the nail into the wood.

How do you drive a nail on a board?

A tried and true technique is to turn the nail upside down with the head resting on a hard surface and the tip facing up. Then, lightly tap the nail tip with your hammer to slightly blunt it. A slightly blunted nail is really no more difficult to drive, and it almost never will split the wood.

What is the force due to gravity on an object?

The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg.

Does a 2 kg rock have twice the mass of a 1 kg block?

Yes, a 2- kg rock has twice the mass of a 1-kg rock, since mass is measured in kilograms. Yes, the 2-kg rock also has twice the inertia, since, for our purposes, mass and inertia are the same thing. Volume – the amount of space an object occupies – is measured in liters (for liquids).

What is the action and reaction in hammering a nail?

A hammer hits a nail, driving the nail downwards into a piece of wood. The “reaction” is the force of the nail pushing upwards on the hammer, which stops the hammer. You are standing on the floor.

What is the reaction force of a hammer hitting a nail?

The reaction force will be equal to the force exerted by the hammer on the nail. This is because of the newton’s third law of motion which says that for every action there is equal and opposite reaction.

What determines the force on the bed of nails?

The force is determined by the weight of the person lying on the bed of nails. The area is determined by the effective area of the tip of the nail, or nails, in contact with the skin. If there were only one nail, the entire force created by the weight of the body would be distributed over the very small area presented by the tip of the one nail.

What is the ‘secret’ to nail piercing?

The ‘secret’ to this phenomenon is first to understand that it is the force per unit area of skin (i.e., pressure) that determines if a nail will pierce the skin. The force is determined by the weight of the person lying on the bed of nails.

What happens when you touch a pie pan with a nail?

When you touch a positively charged pie pan to the nail on the Leyden jar, electrons from the nail flow onto the pie pan. The resulting positive charge on the nail attracts electrons from your body through your hand onto the aluminum foil of the jar.

How do you use aluminum foil in an electrostatic experiment?

You may tape the aluminum foil in place. Fill the film canister almost full with water, then snap on the lid. The nail should touch the water. Rub the upside-down foam plate with the wool cloth. If this is your first time using the foam in an electrostatic experiment, rub it for a full minute.
