... that can be used to determine if the equilibrium points (i.e. points where dV /dx = 0) are stable or unstable. This test is based on looking at the value of the second derivative of the potential at the equilibrium point. That is if d2 V /dx2 > 0 then the equilibrium point corresponds to a minimum o ...

... If we extend the basic idea of a cannon recoiling from the cannonball it launches, we can understand rocket propulsion. Consider air escaping from an untied, blown-up balloon. If the balloon is released and allowed to move as shown in Figure 7.8, it accelerates as the air comes out. A rocket accele ...

... Common pupil mistake: Some people think that because the atmosphere is a thin layer around the Earth, and there’s no air in space, the same applies to the force of gravity. But gravity gets less gradually as you move away from the Earth, and is still a sizeable force far above the top of the atmosph ...
