Define uniform circular motion? Is it an accelerated motion? If yes, what is the direction of acceleration? Guve an example of this type of motion
Answers
Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction.
yes it is aclerated motionWhen an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down
Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a 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
Hey, there your answer is __________,
Answer: The motion of an object along a circular path is circular motion. And, when a body moves along a circular path with constant (uniform) speed, its an uniform circular motion.
Yes, it is an accelerated motion.
When an object moves along a circular path with constant (uniform) speed, the only change in its velocity, is due to change in direction of motion. So, it is an accelerated motion, where magnitude of velocity is constant but its direction changes at each point.
Examples of uniform circular motion are as follows-
i) The moon moves around the earth in a circular path.
ii) A stone is tied to a string when rotated, give rise to circular motion of the stone.
Hope it helps u...!
