a subatomic particle having a positive charge and which is
found in the nucleus of an atom
What is proton
100
internal energy found by adding the kinetic energy of
particles making up a substance
What is Thermal energy
100
a type of simple machine that consists of a rod driven
through the center of a cylinder that is allowed to rotate
freely, yielding a mechanical advantage equal to the
cylinder’s diameter

the event, condition, or factor that can be changed or
controlled in order to study or test a hypothesis in a
scientific experiment
What is variable
200
the distance between crest of a wave
the time-rate at which a body changes its position; defined
as displacement divided by the time of travel

300
the lowest point on a wave
What is trough
300
a particle, object, or system that lacks a net charge
What is neutral
300
energy stored in an object due to the object’s configuration
and position
What is potential energy
300
a measure of the amount of space an object takes up; also
the loudness of a sound or signal
What is volume
400
amount of distance traveled divided by time taken; the time-rate at which any physical process takes place
What is speed
400
a substance that cannot be reduced to a simpler substance

400
the energy possessed by a body because of its motion
What is kinetic energy
400
a repetitive movement around an equilibrium point
What is vibration
500
the property of an object, due to its mass, that causes it to
resist any change in its motion unless overcome by a force
What is

500
the smallest unit of a chemical element that can still retain
the properties of that element
What is Atom
500
a form of energy resulting from the temperature difference
between a system and its surroundings
What is heat
500
a type of simple machine; a circular lever, usually a wheel
with a groove where a rope can be placed and used to
change the direction of a force
