Below are sample questions representative of the exercises included on this worksheet and related 12.49 Energy in Gravitational Systems skill assessments:

Problem 1Difficulty: Mastery

Which summary correctly compares falling, circular orbiting, and escaping after engine cutoff in an ideal gravitational field?

AFalling inward converts K to U; circular orbiting eliminates U; escaping outward converts U to K.

BAll three motions require total mechanical energy to increase.

CAll three motions have zero total mechanical energy because gravity is conservative.

DFalling inward converts U to K; circular orbiting keeps K and U constant; escaping outward converts K to U.

Solution & Explanation:The direction of motion relative to gravity determines the energy tradeoff. Circular motion at fixed radius keeps K and U constant, while ideal coasting conserves total energy.

Problem 2Difficulty: Mastery

A satellite in a circular orbit suddenly loses a small amount of kinetic energy due to a retrograde impulse. Immediately after the impulse, before its radius changes much, what is true?

AIts total mechanical energy is higher because it will fall inward.

BIts total mechanical energy becomes zero because the orbit is no longer circular.

CIts total mechanical energy is lower and its path becomes a lower-energy bound orbit.

DIts gravitational potential energy changes instantly by the same amount as kinetic energy.

Solution & Explanation:At the instant of the impulse, radius and U have barely changed, but K decreases. Therefore total mechanical energy decreases and the orbit changes.

Problem 3Difficulty: Mastery

A probe falls inward from rest at infinity and later passes radius r. What total mechanical energy and speed condition does it have at r?

ATotal energy is negative, and its speed equals circular speed.

BTotal energy is zero, and its speed equals local escape speed.

CTotal energy is positive, and its speed exceeds escape speed.

DTotal energy is zero, and its speed is zero.

Solution & Explanation:Rest at infinity corresponds to E = 0. Conservation of energy then gives K = -U at radius r, which is exactly the escape-speed condition.
