force
4
a push or a pull that causes an object to move, stop, or change
direction
5
gravity
6
the force that pulls all things in the universe toward each other; the force
that pulls things down on Earth
7
magnetism
8
a force that pulls iron or steel across a distance; a force that attracts or
repels magnetic material

friction
10
a force that resists motion when objects rub against each other
11
motion
12
a change in the position of an object
13
Simple machine
14
a device with few or no moving parts that changes the size or
direction of a force

energy that flows through a circuit and can create light, heat,
magnetism, sound, or other effects
19
Electric circuit
20
a closed path where electricity can flow

the direct transfer of heat between objects that touch
27
convection
28
heat moving from one object to another caused by mixing a liquid or
a gas
