Define uniform circular motion. Give an example also. Write the formula to calculate speed of an object undergoing uniform circular motion. Is it an accelerated motion? Explain.
Answers
Answer:
The motion of a body moving in a circular math with constant speed about a particular point is called UCM
E.g. Motion of moon around earth,electrons around nucleus,etc.
v = rw (w=angular velocity of the particle undergoing UCM)
Yes. It is an accelerated motion as the velocity of the body being a vector quantity changes every instant as the direction of motion also changes every instant even though the speed doesn't change. Direction of velocity at any instant is along the tangent drawn to the circular path at that point. Hence it is accelerated motion

Answer:
In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a ceiling fan's blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, ...

v = r ω v = r \omega v=rω v v v is linear speed, r is radius, ω is angular speed.
T = 2 π ω = 1 f T = \dfrac{2\pi}{\omega} = \dfrac{1}{f} T=ω2π=f1 T T T is period, ω is angular speed, and f is frequency.
