You need to be able to attempt the question yourself. We can help you when you get stuck.Sarina3003 said:Thanks for that. However, i don't quite follow you ;(
Tom's suggested experiment is very easy. With a light overhead, rotate your arm in front of you so that your hand moves in a vertical circle at a constant rate. Watch the shadow. When the shadow is moving most slowly, what is yiur hand doing? What about when the shadow moves fastest?Sarina3003 said:Thanks for that. However, i don't quite follow you ;(
Good reasoning. The horizontal component of motion is indeed SHM.Sarina3003 said:Thank you. However it's really hard
to see by naked eyes and my hands could not move at a constant rate eithe. But i think it could be B because i have thought of simple harmonic motion :|. B is equilibrium postion and V is max there , not really relevant but that's the only thing that my brain could say to me :(
Uniform circular motion is a type of motion in which an object moves along a circular path at a constant speed. The object's velocity is always tangential to the circular path and its acceleration is directed towards the center of the circle.
The main difference is that in uniform circular motion, the object moves at a constant speed, while in non-uniform circular motion, the speed changes at different points along the path. Additionally, the acceleration in uniform circular motion is always directed towards the center, while in non-uniform circular motion, the acceleration may have both tangential and radial components.
The centripetal force is the force that acts towards the center of the circular path and keeps the object moving in a circular motion. It is always perpendicular to the velocity of the object and is responsible for continuously changing its direction.
Uniform circular motion is a special case of angular motion, where the object moves along a circular path at a constant speed. The angle swept out by the object in a given time interval is directly proportional to its linear speed and the radius of the circular path.
Some examples include a car driving around a roundabout, a satellite orbiting the Earth, a Ferris wheel, and a spinning top. Any object that moves along a circular path at a constant speed can be considered an example of uniform circular motion.
