Chapter 7: Circular Motion and Gravitation
... According to Kepler’s second law, if the time a planet takes to travel the arc on the left (∆t1) is equal to the time the planet takes to cover the arc on the right (∆t2), then the area A1 is equal to the area A2. Thus, the planet travels faster when it is closer to the sun and slower when it is far ...

... When is Newton’s first law valid? • In Figure 4.11 no net force acts on the rider, so the rider maintains a constant velocity. But as seen in the noninertial frame of the accelerating vehicle, it appears that the rider is being pushed. • Newton’s first law is valid only in non-accelerating inertial ...
