Question

Which of the following statement is incorrect about a body undergoing a uniform circular motion?
1. In Uniform Circular Motion the body moving in circle is accelerating
2. In Uniform Circular Motion the body is changing direction but the speed remains constant
3. All of the above
4. In Uniform Circular Motion the velocity of body remains constant

Answer 1

Correct Answer - Option 4 : In Uniform Circular Motion the velocity of body remains constant

The correct answer is In Uniform Circular Motion the velocity of the body remains constant.

• In Uniform Circular Motion the velocity of a body remains constant is the incorrect option for uniform circular motion.

​

• ​Uniform circular motion can be described as the motion of an object in a circle at a constant speed.
• As an object moves in a circle, it is constantly changing its direction.
• Although the speed of the body remains the same the velocity is changing due to the change in the direction.
• An object moving in a circle is accelerating.
• Accelerating objects are objects which are changing their velocity either the speed (magnitude of the velocity vector) or the direction.
• An object undergoing uniform circular motion is moving at a constant speed.
• Nonetheless, it is accelerating due to its change in direction.
