The Force Vector and Simple MachinesForce is relatively easy to intuit as a vector. The force vector points in the direction in which it is trying to accelerate the object it is acting on. Since force vectors are so much easier to visualize than acceleration vectors, it is often helpful to first find the direction of the (total) force vector acting on an object, and then use that information to determine the direction of the acceleration vector. Newton's second law, F_{total} = ma, tells us that the two must be in the same direction.
