Unifrom circular motoin (UCM)
Answers
1)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. At all instances, the object is moving tangent to the circle.
2)Uniform Circular Motion Examples
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 wind mills.
3)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.
4)V = 2π r / T
Any object moving in uniform circular motion also has an angular velocity. The object's velocity changes continuously and therefore there is an acceleration in the circular motion, and this acceleration is always directed towards the center of the circle which is termed as centripetal acceleration.
i hope it helpfull to you
When a body moves in a circular path at a constant speed it's motion is said to be uniform circular motion.
hope this helps u❤️
