What are the differences between centripetal and tangential acceleration?
Centripetal: Changes direction, not speed (perpendicular to velocity). Tangential: Changes speed, not direction (parallel to velocity).
Compare period and frequency in uniform circular motion.
Period (T): Time for one revolution. Frequency (f): Revolutions per unit time. Relationship: f = 1/T.
What is the effect of centripetal acceleration on an object's velocity?
Changes the direction of the velocity but not its magnitude (speed).
What is the effect of tangential acceleration on an object's speed?
Increases or decreases the tangential speed of the object.
What force causes centripetal acceleration for satellites in circular orbits?
Gravity provides the centripetal force.
What happens to the orbital period of a satellite if its orbital radius increases, according to Kepler's Third Law?
The orbital period increases.
What happens when a car moves around a banked curve?
Static friction and the normal force combine to create the centripetal force, allowing the car to turn.
