WebNewton’s law of gravitation can be expressed as. F → 12 = G m 1 m 2 r 2 r ^ 12. 13.1. where F → 12 is the force on object 1 exerted by object 2 and r ^ 12 is a unit vector that points from object 1 toward object 2. As shown in Figure 13.2, the F → 12 vector points from object 1 toward object 2, and hence represents an attractive force ... WebNewton’s Law of Gravitation.
