Question

When a particle is in uniform circular motion it does not have:

• A. radial velocity and radial acceleration
• B. radial velocity and tangential acceleration
• C. tangential velocity and radial acceleration
• D. tangential velocity and tangential acceleration

Answer 1

The correct option is B radial velocity and tangential acceleration

In uniform circular motion:

• tangential speed is constant so tangential acceleration is 0.
  
• and radius of circle is constant hence radial velocity is 0
  

When a particle is in uniform circular motion it does not have radial velocity and tangential acceleration.
