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 is the cause and the outcome of rotational motion?
The cause of rotational motion is a force towards a fixed point called centre of curvature. The outcome of rotational motion is the tendency of the rotating body to move radially- (eg) outward shifting of objects in a car as it takes a curved path.
Is an example of rotary motion?
The rotational motion of an object on a fixed axis. IE - A Wheel on a car. Theoretically speaking, there is no such thing as rotational force. The molecules are trying to move in a strait line, but are being pulled back by the axis bond.
What keeps the air in constant motion?
Well, since the earth is moving, the air moves arounds the earth. So, the rotation of the earth makes air move in constant motion.
Definition of molecular motion?
Molecular motion is how atoms move. They will move differently depending on what kinds of energy are stimulating it and these motions are measured using temperature.
Do the particles in solids move?
Particles within are limited to vibrational motion, unlike the particles which make up liquids which can have vibrational & translational motion, and gaseous particles which have vibrational, translational and rotational motion.
When applying a force to make an object move why is it most effective to have the applied force aimed directly at the objects center of mass?
The question is based on the false assumption that imparting a rotational motion on an object is not making it move.Applying the force which is not aimed directly at the centre of mass imparts a rotational as well as a translational motion. Why should this be considered any less than only rotational or only translational motion?
What is Rotational motion in physics?
there are three ways something can move: translational -- like my car going down the road vibrational -- like a slinky or spring rotational -- like a baton that twirls end over end. When studying rotational motion, certain additional vocabulary words become important: frequency, moment of inertia, etc.
How are the particles in a solid?
Particles within are limited to vibrational motion, unlike the particles which make up liquids which can have vibrational & translational motion, and gaseous particles which have vibrational, translational and rotational motion.
What effect would decreasing the temperature have on Brownian motion?
As temperature decreases, the energy of the molecules decreases. Since the energy of the molecules is stored in their translational, vibrational, and rotational motion, their overall motion will decrease and consequently the Brownian motion that results from their motion will diminish as well.

How does the earth move about the sun?
In a rotational pattern.

What is the movement of atoms in a liquid during a temperature changes both increases and decreases?
As temperature increases, the atoms will move around more energetically - moving on average faster. Translational speeds increase, rotational speeds of the molecules increase, and the magnitude of vibrations of the atoms about their bonds in molecules increase As temperature decreases, the atoms move around less energetically - moving on average slower. Translational speeds decrease, rotational speeds of the molecules decrease, and the magnitude of vibrations of the atoms about their bonds in molecules decrease
What is molecule movement?
Molecular MotionMolecules and everything in them can move in many ways, and energy is associated with all of those different kinds of motion. There is translational movement. Molecules can move from one place to another.There is also rotational movement. That is, they can turn around and around.The third way shown here is vibrational movement.In addition, electrons can move from place to place and orbital to orbital.These types of motion and the energy associated with them influence the physical properties of chemicals. The color of chemicals is often associated with changes in electron energy levels.The phase of chemicals is associated with translational and rotational motion of molecules. In the gas phase molecules are free to move from one place to another and also have considerable translational motion.Rotational motion can involve the entire molecule rotating or the internal parts of the molecule rotating with respect to one another. These types of rotation are found in molecules in both the gas phase and the liquid phase.Vibrational motion is found in molecules in all three of the phases. It is the vibrational motion and the energy needed to change it that we will focus on now.
