8. Centripetal Forces & Gravitation

A flywheel in the form of a uniformly thick disk of mass $M$ and radius $R$ rotates about its central axis. What is its moment of inertia about this axis?

When analyzing uniform circular motion, does the direction (clockwise or counterclockwise) of a merry-go-round affect the magnitude of the $\mathrm{centripetal} \mathrm{acceleration}$ experienced by a rider?

An object moves in uniform circular motion with a constant angular speed of $\omega$ radians per second. How many complete revolutions does the object make during the first $4$ seconds?

While a car travels around a circular track at a constant $v$ (speed), its $\overrightarrow{v}$ (velocity vector) changes because its direction is continuously changing. Which of the following quantities remains constant during this motion?

An object is moving in uniform circular motion. What will happen to the object's motion if the $F{c}_{\mathrm{entripetal}}$ force is suddenly removed?

In uniform circular motion, which force is commonly (but incorrectly) thought to push a vehicle away from the center of the road during a turn?

Which formula can be used to find the tangential speed of an object moving in uniform circular motion?

When your clothes spin around in the dryer, which force is primarily responsible for keeping them moving in a circular path?

Which of the following statements is true about an object in $uniform$ circular motion in a circular orbit?

A flywheel with a diameter of $1.20m$ is rotating at a constant angular speed. What is the magnitude of the centripetal acceleration at a point on the rim if the angular speed is $5.00\mathrm{rad}/s$?

Which of the following is constant for an object in uniform circular motion?

Which statement correctly describes the force responsible for uniform circular motion?

In the context of uniform circular motion, what is the correct way to adjust your $v$ (speed) when approaching and traveling through a curve to maintain control and safety?

Why does a satellite in a uniform circular orbit travel at a constant speed?
