Circular motion


From Yahoo Answers

Question:the concept is from physics, reveal the truth and misconception related to it

Answers:The movement may be sustaining a constant speed, but the body receives a constant acceleration: the centripetal force. If this force is of constant amplitude, it however changes constantly in direction!

Question:hi folks! need sample problems with sol'n about uniformly accelerated motion with 2 object as given. tnx

Answers:consult a physics book.. they have a lot of problems there. =D

Question:Hello, I am a bit confused as to what Uniformly Accelerated Motion Is: Here are a few questions: 1. Is uniformly accelerated motion and uniform accelerated motion the same? 2.Here is my explanation: Uniformly Accelerated motion is when the acceleration stays as a constant (doesn't it get faster and faster though?) and is based on the magnitude of force that pulls the cart (gravity?) 3. Does uniform accelerated motion have do with naturally accelerated motion? 4.Did galileo contribute to this notion? 5. What is the difference with acceleration and speed? For an example a ball rolling down a ramp is uniform accelerated motion. Also, do I graph it with time and velocity as x and y ? Lastly, any good websites on this topic? If you just know a good website explaining this thoroughly, then please feel free to just post that. It would be as helpful as answering the questions Thanks~

Answers:1) yes, just know it as "constant acceleration" or acceleration is constant 2) OK as long as U recognize the DIFFERENCE between velocity and acceleration. These are not the same, and usually one speaks about velocity as being or not being "faster and faster" so I'm just a bit in doubt here. 3) yes, in the sense that "g" the CONSTANT acceleration of gravity = 9.81 m/s in the SI system is acting on us (on the earth) at all times. 4) yes 5)acceleration represents CHANGE in velocity or speed NOT these variables themselves. U can graph IT anyway U like, but usually time (the independent variable) is on the x-axis when plotting motion graphs. just google it - many good sites, not able to search for U


Answers:When acceleration is 0, velocity will not change and the movement will be through a straight line. Don't forget that accelerations and velocities are vectors. So, while the speed is the same in uniform circular motion (speed is the module of the velocity, that is, the length of the velocity vector), velocity changes direction. And for that effect, there need be an acceleration towards the center of the circle. That's the centripetal force. Example: the Moon around the Earth. The centripetal force of the circular movement of the Moon is known as gravity. (Actualy, that is not exactly circular, but that is not what you asked for)
