If a particle is moving with uniform circular motion, then:
Correct answer: C. Velocity and acceleration are perpendiculars
- A. Velocity and acceleration are antiparallel
- B. Velocity and acceleration are parallel
- C. Velocity and acceleration are perpendiculars
- D. Zero acceleration
Explanation
The correct option is C, "Velocity and acceleration are perpendicular." This option is correct. In uniform circular motion, the velocity and acceleration vectors are always perpendicular to each other. The velocity is tangential to the circular path, while the acceleration (centripetal acceleration) points toward the center of the circle.

About Angular Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
