Red vs Blue

Classical Mechanics Level 2

You drop two identical ellipsoid-shaped objects from identical heights. The ${\color{#3D99F6} \text{blue} }$ one falls straight down and the ${\color{#D61F06} \text{red} }$ one spins while falling.

Given enough trials , what reasonable conclusion can you make from your observations?

Assume there is no air resistance.

The

{\color{#3D99F6} \text{blue} }

one tends to bounce higher The

{\color{#D61F06} \text{red} }

one tends to bounce higher Both will always bounce back to the same height Impossible to answer

The red object will have both rotational and kinetic energy right before hitting the ground. If it hits the ground at the right angle, it will bounce back higher on average.
