Ethan and Joseph are riding on a merry-go-round. Ethan rides on a horse at the outer rim of the circular platform, twice as far from the center of the circular platform as Joseph, who rides on an inner horse. i. When the merry-go-round is rotating at a constant angular speed, what is Ethan's angular speed? a. Twice Joseph's b. The same as Joseph's c. Half of Joseph's d. Impossible to determine ii. When the merry-go-round is rotating at a constant angular speed, describe Ethan's tangential speed from the same list of choices?

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
