What is Newtons First law of motion?!
. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

300

Substances on the left of the chemical equation are called what?

Reactants

300

Periods on the periodic table give you what information?

Number of orbitals.

What are sound waves?

A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.

400

What is the definition of, force?

is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
