<p>Eg., the electrostatic constant and the many things that have to do with heat.</p>
<p>Oh, and maybe the permittivity of free space. </p>
<p>I don’t think so, but check past threads about physics. </p>
<p>No, you don’t. You should keep in my mind the general ideas of them, i.e., gravitational constant is super small and electrostatic constant is really big. Usually the test asks questions that have to do with manipulating the equations. Such as: if a planet’s mass were doubled, what would the effect be on the gravitational force? Or stuff like that.</p>
