Rotational Dynamics
... One of the most common examples of the rigid body’s rotation in everyday life is rolling of the bicycle's wheel or the car's wheel along the road. In fact rolling is not a pure rotation, because the wheels are not only rotating but also performing translational motion along the surface of the road. ...

Newton`s Second Law
... The purpose of Experiment 1 is to find out what happens to an object’s acceleration when the net force applied to the object changes and the mass of the system is held constant. You will then examine the inverse situation - a system under the influence of a constant force but variable mass. Use a mo ...
