Question 1
What is the relationship between linear velocity and angular velocity?
- v = ω/r
- v = rω
- v = ω*r²
💡 Hint: Think about how they are both derived from rotation.
Question 2
True or False: Centripetal acceleration increases with increasing radius.
- True
- False
💡 Hint: Consider the effects of doubling the radius with constant velocity.

Challenge Problems
Push your limits with challenges.
Question 1
A rotating platform has an angular velocity of 2 rad/s. Calculate the linear velocity of a point 3 meters from the axis of rotation.
💡 Hint: Apply the formula for linear velocity based on the radius.
Question 2
If an object moves in a circle of radius 4 m at a speed of 16 m/s, what is its centripetal acceleration?
💡 Hint: Centripetal acceleration relates to how fast the object is moving and its distance from the center.
