Key Points

  • The direction of the acceleration is inwards. The acceleration in a uniform circular motion is along the radius and towards the center.
  • The movement of a body following a circular path is called a circular motion.
  • The motion of a body moving with constant speed along a circular path is called Uniform Circular Motion.
  • In this motion speed is constant but the velocity changes.
  • In the case of uniform circular motion, the acceleration is ar = v2/r = ω2r.
  • A particle is moving in a uniform circular motion:
    • Velocity is changing at every instant.
    • There is no tangential acceleration.
    • Its speed is constant.

Additional Information

  •  Examples for Circular Motion:
    • The motion of blades of the windmills.
    • The tip of the second hand of a watch with a circular dial shows uniform circular motion.
    • The motion of electrons around its nucleus.

What is the correct answer for acceleration of uniform circular motion?

In uniform circular motion, acceleration is zero.

Which motion is uniform circular motion?

uniform circular motion, motion of a particle moving at a constant speed on a circle. In the Figure, the velocity vector v of the particle is constant in magnitude, but it changes in direction by an amount Δv while the particle moves from position B to position C, and the radius R of the circle sweeps out the angle ΔΘ.

What is uniform circular motion Class 9 short answer?

What is Uniform Circular Motion? The movement of a body following a circular path is called a circular motion. Now, the motion of a body moving with constant speed along a circular path is called Uniform Circular Motion. Here, the speed is constant but the velocity changes.

What is uniform circular motion write its formula?

Therefore for an object to move along a circular path, there must be an acceleration that will always be perpendicular to the velocity. The circular motion may be uniform as well as non –uniform. ... a_{rad} = \frac{4{\pi}^2 R}{T^2}.
