Question

What is Uniform circular motion??​

Answer 1

$\sf\red{Uniform \: circular \: motion:-}$

• When an object moves on a circular path with constant or uniform speed, it is said to have uniform circular motion.

For example:-

1. motion of hands of a clock,
2. motion of moon revolving around the earth.

Answer 2

$\small \mathsf{ \color{p}{Uniform \: circular \: motion}}$

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 cónstant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.

$\small \mathsf{ \color{red}{Calculation}}$

She shows that the equation to calculate circular velocity is v = (2 * Pi * r) / T, where r is the radius of the circle the object moves in, and T being its time períod.

$\small \mathsf{ \color{red}{Magnetic \: \: field}}$

Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. ... The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.

Uniform Circular Motion Examples

Following are the examples of uniform circular motion:

• Motion of artificial satellites around the earth is an example of uniform circular motion. The gravitational force from the earth makes the satellites stay in the circular orbit around the earth.
• The motion of electrons around its nucleus.
• The motion of blades of the windmills.
• The tip of second’s hand of a watch with circular dial shows uniform circular motion.
