• ﻿Bro, so, my owner is doing his homework and he asked me to help. I don't think he wants me to eat it again.
• Uniform circular motion? Well, it is when anything moves in a circle with a constant speed.
• Uhh... so what the heck is unicorn cola motion?
• No, dood... no
• The force that keeps the thing moving in a circle is centripetal force
• What?! Centipedes? I hate them!
• ... Pretend you're not... So, first, the formula for the velocity of an object in unifrom circular motion is V=[(2pi)*r]/T. In this case, r is the radius, and T is the period
• Ok, so, let's try a problem... You're on a Ferris wheel. Find the velocity of it if the period equals 1200 seconds and the radius of the wheel is equal to 20 meters.
• Uhh... I have a height phobia.
• MIND BLOWN! How about the centripetal acceleration?
• After plugging all the numbers and the pi value into the formula, we will get a velocity of 0.0167 meters/seconds.
• That is the acceleration of an object in uniform circular motion. The formula for acceleration is a=v^2/T, in which v is velocity and T is period.
• YEP! Now, go spread the wise words, my prophet!
• OHHHHH! So, if we plug in the numbers using the same example, we would get an acceleration of 0.000000232 m/s^2 right?
