Newton`s Laws of Motion
... 1. Misconception - A force is needed to continue the objects motion An object can fly through space with a constant velocity as long as no external forces act on it (unbalanced force). 2. Misconception – There are no forces in spaces A spaceship can be accelerated if acted upon an external force (ex ...

Impulse, Momentum and Conservation of Momentum
... Conservation of Momentum Newton’s Third Law: The potato goes one way and the gun “recoils” in the opposite direction. The gun exerts a force on the potato and the potato exerts an equal but opposite force on the gun, recoil. ...

... In regards to relativity, you need to understand the material from Chapter 14 Classical Dynamics by Thornton and Marion. Another topic that is often explored concerns fundamental conservation laws. A standard text that describes conservation of baryon number, lepton number, etc., should be fine. The ...
