Storyboard Text

  • 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?
