Below are sample questions representative of the exercises included on this worksheet and related 12.46 Orbital Speed and Period skill assessments:

Problem 1Difficulty: Mastery

Which summary correctly describes circular orbits around one central mass?

ASmaller circular orbits have lower speed, shorter period, and smaller angular rate.

BLarger circular orbits have higher speed, shorter period, and larger angular rate.

CAll circular orbits around one mass have the same speed and period.

DSmaller circular orbits have higher speed, shorter period, and larger angular rate.

Solution & Explanation:For one central mass, v decreases with radius, T increases with radius, and angular rate 2 pi/T decreases with radius. Therefore smaller orbits are faster and repeat sooner.

Problem 2Difficulty: Mastery

Use the comparison diagram in the image. An orbit changes from central mass M and radius r to central mass 4M and radius r/4. Which new speed and period are correct?

Aspeed is 2v and period is T/4

Bspeed is 16v and period is T/4

Cspeed is 4v and period is T/16

Dspeed is v/4 and period is 16T

Solution & Explanation:Speed factor is sqrt(4/(1/4)) = 4. Period factor is sqrt((1/4)³/4) = sqrt(1/256) = 1/16.

Problem 3Difficulty: Mastery

Use the table in the image. Four satellites list scaled radius r and period T. Which satellite likely orbits a different central mass?

ASatellite A

BSatellite D

CSatellite B

DSatellite C

Solution & Explanation:For one central mass, T²/r³ is constant. A, B, and C each give 1 in scaled units; D gives 16/64 = 0.25, so it suggests a different central mass.
