WAIT…DON’T FORGET…  For 9 th -10 th Accuracy 1/8 “ Diameter

 Energy from spring is transferred to car via the lever arm  Lever arm provides torque required to turn axles  Energy from spring is transferred to car via the lever arm  Lever arm provides torque required to turn axles Length of lever arm affects power output Shorter arm = faster output Longer arm = slower output

 # of wheels : 3 or 4  Wheel radius  The greater the radius, the greater the torque required to rotate the axle  Wheel grip (traction)  Essential for going up a ramp  Power output must match wheel grip to avoid spinning  Ratio of wheel-to-axle  Larger ratio good for distance, but not necessary for accuracy and power  Friction  Reduce friction between wheels and surface  Also between axle and chassis  Alignment  # of wheels : 3 or 4  Wheel radius  The greater the radius, the greater the torque required to rotate the axle  Wheel grip (traction)  Essential for going up a ramp  Power output must match wheel grip to avoid spinning  Ratio of wheel-to-axle  Larger ratio good for distance, but not necessary for accuracy and power  Friction  Reduce friction between wheels and surface  Also between axle and chassis  Alignment
