... The negative sign simply means the force is attractive. Most orbit problems can be solved by setting the gravitational force equal to the centripetal force. Gm1m2 / r2 = m1v2 / r (a good starting point for most problems!) Orbit – the above equation simplifies to v = √GM/r for velocity in an orbit wh ...

... The first step in solving a collision problem is to determine the type of collision. You can’t assume that; the problem must tell you either directly or indirectly. Obviously if they simply tell you the type of collision, that’s fine. On the other hand, they could tell you indirectly through hints. ...
