- I can help you then. What is it about?
- PhySicS
- 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?
