801-C: Rotational Velocity Conversions

BACK to Ladder Rotational Kinematics

The SI unit for angular velocity is radians per second. However, it is frequently presented with a different unit, namely, radians per second.

Other unit

Here are two non-SI but very common units for angular velocity: $$ \text{rps} = \text{rotations per second} = \frac{\text{rotations}}{\text{second}} $$ and $$ \text{rpm} = \text{rotations per minute} = \frac{\text{rotations}}{\text{minute}} $$

You can convert these to quantities using the following conversion factors

Convert each of the following quantities to radians per second, the SI unit, using the conversion factor method correctly.

  1. Convert 50 rps to radians per second.
  2. Convert 120 rps to radians per second.
  3. Convert 2 rpm to radians per second.
  4. Convert 30 rpm to radians per second.
