Question

Explain the requirements for a particle to perform uniform circular motion.​

Answer 1

$\huge(Answer)$

1. ☞In uniform circular motion, the particle executing circular motion has a constant speed and the circle is at a fixed radius. If the speed of the particle is changing as well, then we introduce an additional acceleration in the direction tangential to the circle.

Answer 2

Particle to perform uniform circular motion:

Explanation:

• When a particle with a fixed point as its center moves in a circular path around it with a uniform speed, then its motion is called uniform circular motion. For example, the speed of the tip of a clock's hand.
• If a particle travels a distance As on a circular path in a small time interval At (= t2-t1) and during this time the particle rotates at an angle A0 at the center 0.
• Circular motion - When an object moves along a circular path If so, its motion is called circular motion.
• If it moves with a uniform speed, then its motion is called uniform circular motion.
• Uniform circular motion is an accelerated motion because the direction of velocity changes at each point.
