Non-contact Forces

non contact force

gravity

A force of attraction between objects that is due to their masses.

projectile motion

the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth

magnetism

The force of attraction or repulsion of magnetic materials

electricity

A form of energy caused by the movement of electrons.

insulator

A material that does not allow heat or electrons to move through it easily.

conductor

A material that allows heat and electricity to pass through it.

magnet

any material that attracts iron and materials that contain iron

magnetic domain

groups of atoms with aligned magnetic poles

magnetic field

the region around a magnet where the magnetic force is exerted

gravitational field

a force field that exists in the space around every mass or group of masses

electric field

the space around a charged object in which another charged object experiences an electric force

force fields

Region in space affected by a force at a distance

field lines

Lines coming from an object representing the strength of the force. The denser the lines, the stronger the force.

electromagnet

A type of magnet in which the magnetic field is produced by an electric current. A current through the wire creates a magnetic field around a metal rod.

Generator

A moving magnetic field flowing around a wire will make electricity. It turns mechanical energy into electricity.
