When trying to figure out how much attractive or repulsive force exists between two objects we have to use Coulombs law which includes a constant. Why do we need to use the constant, how could you figure out what the constant is (actually figure it out, not look it up), and why is or isn't it a problem that the gravitational

Frame of reference

In physics, a frame of reference is a coordinate system used to specify either the position or the orientation or velocity of a body. The origin of the coordinate acts as a reference point for measuring the position or relative motion of a body. The coordinate system can be a cartesian coordinate, cylindrical coordinate, or a polar coordinate.
