Measured Turn

1. The left wheel spun.
2. i) a circle
ii) The stopped right wheel.
iii) The left moving wheel.
iv) yes
3.i) 28.5 cm
ii) 89.5 cm
iii) degrees/360=x/89.5
4.i) They are two completely different circles.
ii)wheel
iii) circle on ground
5. (degrees of circle/360)*(circumference of circle)=(circumference of wheel)*(motor degrees/360)
442.1 degrees
6. i) yes
ii) yes, the calculations worked
iii) You cannot prove a hypothesis with one test.
7. i) 885.2 degrees
ii) 1327.7 degrees
iii) 1770.3 degrees
iv) 3540.7 degrees
8. i-iv) done
v) they all work so it supports the hypothesis
9. i)6 cm
ii)it was very close to 90 degrees
iii)yes
iv) 14cm radius
10. i) due ti different sizes have different turning radii.
ii) car, 25-50 ft
iii) swing turn
11. (210/360)pi*2*12.4=pi*4.5(x/360)
x=1157.3
12. (180/360)pi*2*9=pi*2.5(x/360)
x=1296
13. i) 4.6 diameter wheel will be closer to the correct diameter needed
ii) he can shrink the distance between the two wheels of his robot
