How does uniform circular motion differ from uniform linear motion ?
Topic: Force, moments and circular motion
Previous-year question practice database
Answer
Exam answer
Uniform circular motion has constant speed but changing velocity and centripetal acceleration; uniform linear motion has constant velocity and zero acceleration.
Comparison
| Uniform circular motion | Uniform linear motion |
|---|---|
| Velocity changes direction; acceleration is centripetal. | Velocity is constant; acceleration is zero. |
