Rotational Kinetic Energy
Rolling
Total Kinetic Energy = Kcm + Krot
Why does a rolling
sphere slow down? :thinking_face:
No real sphere is perfectly rigid.
The bottom will deform, and the normal force will create a torque that slows the sphere
The normal force exerts a torque that slows down the sphere. The deformation of the sphere and the surface it moves on has been exaggerated for detail.
