Below are sample questions representative of the exercises included on this worksheet and related 12.43 Circular Motion in Real World Systems skill assessments:

Problem 1Difficulty: Mastery

A student says, 'A car slides outward on a curve because centrifugal force pushes it away from the center.' Which inertial-frame explanation is more accurate?

AA real outward force grows until it beats friction

BGravity pushes sideways whenever a car turns

CThe normal force disappears, so the car moves directly outward

DIf inward friction is insufficient, the car continues more nearly tangent while the road curves away

Solution & Explanation:In an inertial frame, the car needs inward friction to curve with the road. If that force is too small, the car does not get enough inward acceleration and continues closer to its tangent line.

Problem 2Difficulty: Mastery

A satellite at radius r around a planet is given a speed 10% greater than the circular-orbit speed for that radius. Which statement best diagnoses the circular-motion model?

AThe satellite needs an outward force equal to 10% of gravity

BThe satellite's mass must increase so gravity can catch up

CGravity is too small to provide the v²/r needed for a circle at that radius

DThe satellite will still have the same circular orbit because gravity is unchanged

Solution & Explanation:At the circular speed, gravity supplies exactly v²/r. A 10% higher speed requires 1.21 times the inward acceleration for a circle at the same radius, but gravity at that radius is unchanged, so the path cannot remain that circle.

Problem 3Difficulty: Mastery

Two carousel riders have the same tangential speed. Rider A is 2.0 m from the center, and Rider B is 8.0 m from the center. How does Rider A's centripetal acceleration compare to Rider B's?

AIt is twice as large

BIt is four times as large

CIt is one-fourth as large

DIt is the same

Solution & Explanation:For the same tangential speed, a_c = v²/r. Rider A's radius is one-fourth of Rider B's, so Rider A's centripetal acceleration is four times as large.
