Speed of rotation formula - 🧡 Rotational Motion

Example Imagine a small boy tries to make himself dizzy by spinning around rapidly.

A tired fish will be slower, requiring a smaller acceleration and therefore a smaller force.

Until recently, lower-end and power-efficient laptop drives could be found with 4,200 or even 3,600 rpm spindle speeds 70 and 60 Hz , but these have fallen out of favour due to their lower performance, improvements in energy efficiency in faster models and the takeup of for use in slimline and ultraportable laptops.

Furthermore, the more massive the merry-go-round is, the slower it accelerates for the same torque.
