Circular Motion

Question 4 • [HSPHY] Physics Sem 1 (26-27)

In which situation would a space probe most likely experience centripetal acceleration?

Answer
A
as it revolves around a planet
B
as it flies straight past a moon
C
as it is pulled in a line toward the Sun
D
as it lifts off from Earth

Explanation

Centripetal acceleration occurs when an object moves along a curved path, directed toward the center of that path. A probe revolving around a planet continually changes direction, so it experiences centripetal acceleration. Flying straight past a moon or moving in a straight line toward the Sun does not describe circular motion, and lifting off is not necessarily motion around a center.
