Would the Mustang have traveled the quarter mile in this time? (1 mile = 5280 ft.) In the previous question, we determined that 60 mph is the same as 88 ft per second. So, 50 mph would be 50/60 of 88 ft. per sec.

- We can call this the “g-rule”: the force to accelerate an object is equal to the number of gs times the weight . To get the number of gs, just calculate the acceleration in m/s per second, and divide by 9.8. So, for example, we write that an acceleration of a = 19.6 m/s per second = 2 g. This is an acceleration of two gs.

12-1 Newton’s Law of Universal Gravitation G is a very small number; this means that the force of gravity is negligible unless there is a very large mass involved (such as the Earth). If an object is being acted upon by several different gravitational forces, the net force on it is the vector sum of the individual forces. In circular motion, linear acceleration is tangent to the circle at the point of interest, as seen in Figure 2. Thus, linear acceleration is called tangential acceleration[latex]\boldsymbol{a_{\textbf{t}}}.[/latex] Figure 2.
