A block slides (frictionless) and a sphere rolls without slipping down identical inclines starting from the same height. At the bottom,
Both have the same speed.
The sphere is faster.
The block is faster (it has no rotational KE to account for).
Depends on the incline angle.
Explanation
Sliding block: all PE → translational KE → faster . Rolling sphere: PE shared between trans and rot → smaller .
