R.omega^2 has a unit of
Correct answer: C. m/s²
- A. N
- B. m/s¹
- C. m/s²
Explanation
r.omega^2 represents the centripetal acceleration, where r is the radius of the circular path and Ω is the angular velocity. The unit of r is meters (m) and the unit of Ω2Ω2 is (radians/s)². Therefore, the unit of r.omega^2 is m/s^2.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
