6. Intro to Forces (Dynamics)

Which force causes a soccer ball to take a curved path when it is kicked with spin?

In a diagram showing two point masses separated by varying distances, at which location is the gravitational force of attraction between them the greatest? (Recall that the gravitational force between two masses is given by $F=\frac{G}{r}\ast \frac{m\ast m}{r^2}$, where $F$ is the force, $G$ is the gravitational constant, $m$ are the masses, and $r$ is the distance between them.)
