... point nearer the center, the shape of the wheel would be changing. Thus, for a rotating object to remain rigid, as does a bicycle wheel or a Ferris wheel, every portion of the object must have the same angular speed and the same angular acceleration. This fact is precisely what makes angular speed a ...

... surprising. The trajectory of the center of mass is indicated by the downward sloping curve that appears in the vicinity of the large dots. Exercise 1 formally defines the center of mass. We show, in exercise 2, that the trajectory of the center of mass during the initial rolling-without-slipping ph ...

... 3. A gun recoils when it is fired. The recoil is the result of action-reaction force pairs. As the gases from the gunpowder explosion expand, the gun pushes the bullet forwards and the bullet pushes the gun backwards. The acceleration of the recoiling gun is ...
