alleryStart learning →Linear acceleration in circular motion, which changes the size of the velocity, is called:
AGravitational acceleration
BTangential acceleration
CCentripetal acceleration
DAngular acceleration
Answer & Solution
Correct answer: B. Tangential acceleration
1. Two different accelerations act in circular motion.
2. Linear acceleration in that setting is called tangential acceleration.
3. Linear or tangential acceleration refers to changes in the magnitude of velocity but not its direction.
4. Centripetal acceleration does the opposite job.
