deci-
The ability to cause a change in matter.
The power or capacity for activity.
energy
A push or pull
force
The pitch of a sound depends on the ______________of the sound wave.
frequency
The force by which a planet or other body ends to draw objects toward its center.
A force that pulls objects toward each other.

pitch
The energy that an object has as a result of its position or shape. Stored energy that can be released to become other forms of energy.
potential energy
Thermal energy that travels in waves and can pass through empty space as well as some objects.
radiation
A resource such as a solar energy or wood that is inexhaustible or can be replaced by new growth.
renewable resource
Sometimes feel them as vibrations.
sound
