Show hintHide hint
Remember how it feels when you're on a merry-go-round.
3Question 3.
What is the formula for centripetal acceleration?
- ρω²r
- ρg
- ω²r
Show hintHide hint
Look at how these factors relate to circular motion.
4Question 4.
True or False: Centrifugal force is always a real force acting on objects in motion.
- True
- False
Show hintHide hint
Think about how this force is perceived differently based on motion.
Question 5.
A cylinder with a radius of 0.5 m spins at 10 rad/s. Determine the centripetal acceleration experienced by a point on its outer edge.
Show hintHide hint
Apply the centripetal acceleration formula carefully.
Question 6.
In a rotating frame, if the perceived centrifugal force on a mass m is 20 N and the radius is 0.75 m, what is the angular velocity?
Show hintHide hint
Rearrange the equation to find angular velocity.
