Types of Equilibrium

What type of velocity does an object possess if it moves on a straight or curved path?

• Rotational velocity

• Translational velocity

• Angular velocity

• Linear velocity

2. 2. What type of velocity does an object possesses if it moves on a cyclic path?

• Linear velocity
• Centripetal velocity
