A measure of magnetic induction represented by lines of force

An imaginary line roughly parallel to the geographical equator and passing through those points where a magnetic needle has no dip

The portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected

An imaginary line roughly parallel to the geographical equator and passing through those points where a magnetic needle has no dip

A machine by which mechanical energy is changed into electrical energy

An apparatus in which vapor or gas is formed

A mathematical entity that when subjected to one or more operations yields another mathematical entity or its elements

An apparatus for the production of electrical discharges at high voltage commonly consisting of an insulated hollow conducting sphere that accumulates in its interior the charge continuously conveyed from a source of direct current by an endless belt of flexible nonconducting material

Dignity or sobriety of bearing

A serious situation or problem

A fundamental physical force that is responsible for interactions which occur because of mass between particles, between aggregations of matter

The gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface

The force that resists relative motion between two bodies in contact

The clashing between two persons or parties of opposed views

Sound produced by the movement of air through a narrow constriction in the mouth or glottis

Force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.

Acting on an object is the combination of all of the individual forces acting on it.

The sum of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net

When a body is in motion and many forces are active on it like gravitational force Fg, frictional force Ff, and the normal force. Therefore, the net force formula is given by.

In the diagram at left, the net force is 15 Newtons to the right. For example in free fall, the net force on an object equals its weight - the one force pulling on it. If two forces act on an object in opposite directions and they don't exactly cancel, what is left over is the net force (the difference in the forces).

The great body of the people as contrasted with the elite —often used in plural

A quantity or aggregate of matter usually of considerable size

The main part or body

The property of a body that is a measure of its inertia and that is commonly taken as a measure of the amount of material it contains and causes it to have weight in a gravitational field

A neutral glass rod is vigorously rubbed with a cloth, the cloth can remove some of the outer electrons from the rod, leaving it with a net positive charge.

When an uncharged conductor is brought in contact with a charged conductor, charge is shared between the two conductors and hence the uncharged conductor gets charged.

Rubber balloon is charged negatively (perhaps by rubbing it with animal fur) and brought near the spheres, electrons within the two-sphere system will be induced to move away from the balloon. This is simply the principle that like charges repel.

Involves the contact of a charged object to a neutral object. Suppose that a positively charged aluminum plate is touched to a neutral metal sphere.

A device made of an electrical insulating material and used for separating or supporting conductors

A material that is a poor conductor (as of electricity or heat)

Relating to or constituting insulation

Any of a class of solids (such as germanium or silicon) whose electrical conductivity is between that of a conductor at high temperatures and nearly absent at low temperatures

The standard unit of force in the International System of Units (SI), equal to the force that produces an acceleration of one meter per second per second on a mass of one kilogram.

The derived SI unit of force that imparts an acceleration of 1 metre per second to a mass of 1 kilogram; equivalent to 10 5 dynes or 7.233 poundalsSymbol: N

One of the deepest craters on the moon, over 7300 m deep and about 112 km in diameter, situated in the SE quadrant

In the meter-kilogram-second system, the unit of force required to accelerate a mass of one kilogram one meter per second per second, equal to 100,000 dynes.

Of or related to the body

Strength or power exerted upon an object

To drive or propel agaisnt resistance

Strength or energy exerted or brought to bear : cause of motion or change : active power the forces of nature the motivating force in her life.

The electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

An electric field is the force that fills the space around every electric charge or group of charges. There are two types of electric fields: static (or electrostatic) fields and dynamic (or time-varying) fields.

E = F q test = k | Q | r 2 . 18.16. This equation gives the magnitude of the electric field created by a point charge Q. The distance r in the denominator is the distance from the point charge, Q, or from the center of a spherical charge, to the point of interest.

vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field. Thus, the electric field direction about a positive source charge is always directed away from the positive source.

When a charged object is brought closer to another object (not touched),

An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process.

A method used to charge an object without actually touching the object to any other charged object.

Charge in a conductor which is influenced by the charge on another body is known as induced charge.

A person who directs the performance of an orchestra or choir.

A material or object that permits an electric current to flow easily

A person in charge of a train, streetcar, or other public conveyance, who collects fares and sells tickets.

A material capable of transmitting another form of energy (as heat or sound)

Science of charge and of the forces and fields associated with charge. Electricity and magnetism are two aspects of electromagnetism.

A type of magnet in which the magnetic field is produced by an electric current.

Electricity and magnetism were long thought to be separate forces.

A current Through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil.
