Question

Which of the following is the correct formula for centripetal acceleration?
Options
A a = v²r
B a = v/r²
C a = v²/r = ω²r
Correct Answer
D a = ω²/r
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture provides the equivalent formulas for centripetal acceleration: a = v²/r ≡ ω²r.

Hint

Check the units. Acceleration has units of m/s². v²/r gives (m²/s²)/m = m/s².
