For a particle in uniform circular motion (radius R and angular velocity ω), the magnitude and direction of acceleration, respectively are
- A.ωR, along the radius outward
- B.ωR, towards the centre of the circle
- C.ω²R, towards the centre of the circle
- D.ω²R, along the linear velocity
Show answer
In uniform circular motion the speed stays the same but the direction keeps turning, and that change needs an acceleration pointing to the centre.
