The kinematic solution derived above describes the motion at the critical speed.

The critical speed is found from the energy balance:

This star is rotating at about 92% of its critical speed, completing a full rotation every 1.12-1.16 days.

Still he would be glad when they were past the critical speed.

It can also be seen in stroboscopic lights when flashes are set at certain critical speeds.

After a few minutes, the top falls when air friction slows it below the critical speed.

I've got the critical speeds marked off in white, yellow, green, and red.

When the spinning barrel reaches a critical speed, the floor drops out.

The grinding works on the principle of critical speed.

Running into something as big as a human might slow them down below their critical speed.
