Complete Solutions Manual PDF
What is circular motion? - answer-When an object turns about an axis that passes through the
object.
Define axis in the context of circular motion. - answer-The line around or about which rotation
or revolution takes place.
What is rotation? - answer-An object turns around an internal axis, also called spin.
What is revolution? - answer-An object turns around an external axis, also called orbit.
How long does it take for the Earth to rotate around its axis? - answer-Once per 24 hours.
How long does it take for the Earth to revolve around the sun? - answer-Once per 365.25 days.
What is linear speed? - answer-Distance per unit of time, calculated as d/t.
What is tangential speed? - answer-The speed of an object moving in a circular arc.
What is rotational (angular) speed? - answer-The number of rotations per unit of time,
measured in rpm or degrees/sec.
