"Rolling" blocks

I’m doing a bit pf physics, and right now, I have several blocks dropping onto a platform. My issue is where the blocks won’t stop as they usually do, but instead, will roll around.

Thank you!

Look at the scale values of your objects. They should all be 1 not 0.1

Select all objects and apply the scale (Ctrl+A)

Much, much better! Thank you!
