... All projectiles (thrown objects) on earth accelerate DOWN (due to gravity) What does constant velocity mean in term of acceleration and force? Constant velocity means there is zero acceleration. Zero acceleration means zero net force. c. Measure and calculate the magnitude of frictional forces and N ...

The total force on all the particles is a sum of the total external force on the body and the sum of internal forces between particles—but these internal forces come in equal and opposite pairs, from Newton’s Third Law, and therefore add to zero. The bottom line, then, is that the rate of change of ...
