A car moves at the design speed on a frictionless banked curve. Which real force provides the horizontal inward component needed for centripetal acceleration?
Correct answer: A. For the quantitative frictionless banked-curve model, the tilted normal force has a horizontal inward component.
A banked curve requires static friction for a particular speed. Under the current AP Physics 1 boundary, how is this case generally treated?
Correct answer: A. The current framework limits quantitative banked-curve analysis to cases where friction is not required; friction-required cases are qualitative.
Two satellites orbit the same planet in circular paths. Satellite B has four times the orbital radius of satellite A. According to Kepler’s third law, how does B’s period compare with A’s?
Correct answer: A. For the same central mass, T² ∝ R³, so T ∝ R^(3/2). Four to the 3/2 power is 8.
A satellite’s circular-orbit radius around a fixed planet is doubled. By what factor does its orbital period change?
Correct answer: A. Kepler’s third law gives T ∝ R^(3/2), so doubling R multiplies T by 2^(3/2)=2√2.
Two satellites with different masses travel in the same ideal circular orbit around the same massive planet. How do their orbital periods compare?
Correct answer: A. In T²=(4π²/GM)R³, the satellite’s own mass does not appear. Same R and central M give the same period.
Which Kepler-law content is required in AP Physics 1 Topic 2.9 for circular orbits?
Correct answer: A. Topic 2.9.B requires Kepler’s third law for circular orbits; the current boundary says Kepler’s first and second laws are not required.
