Circular Motion Lab

Stop going in circles

question
Question
  • Since speed=distance/time Shouldn’t the fastest line around the track be the shortest one?
what did you experience
What did you experience
  • What did driver’s feel on the inside arc?
  • What is true about the tires on the road?

Arc = portion of circle

frictional force
Frictional Force
  • Ffrict=μ*Fnorm
  • Frictional force is the coefficient of friction times the normal force
  • The coefficient of friction (μ) is determined between two substances empirically. For tires/road it may be high, for tires/ice low.

μ is a Greek letter pronounced mew

At The Racetrack
  • When the kart is turning through a corner of the race track, Centrifugal Force urges the kart to go off the outside of the corner.
  • In order to keep the kart on the track, the Lateral Traction between the tires and the track must balance the Centrifugal Force.

The concept of a “Traction Circle” helps us understand when the kart willlose traction.

The Traction Circle represents the limit of traction available from the tires and their

friction with the track.

If the vector combination of acceleration traction and lateral traction remain inside

the circle, then the kart should remain on the track.

If the vector combination of acceleration traction and lateral traction exceed

the circle, then the kart will slide off of the track.

  • Acceleration is a=v2/r
  • Ffrict=m*v2/r
  • Mass stays constant
  • We are adjusting the radius if the radius increases what else can increase?
  • The Velocity.
