What are a proton, a neutron, and an electron?
Protons have a positive charge, neutrons are neutral and found in the nucleus, electrons have a negative charge and are found outside the nucleus.

What are the three types of heat transfer?
Convection, Conduction, Radiation
What is Newton's first law of motion?
An object in motion stays in motion, and an object at rest stays at rest unless acted upon by another force.
