What i have found out!

  • I have found out that adding pulleys will decrease the lifting weight significantly.
  • That the angle of the pull doesn't change the lifting weights and the results.
  • That the distance traveled by the string doesn't change when using different weights.
  • That for every pulley added to the system it will decrease the lifting weight.

Presenting

I have presented my science fair to the class and I was very unlucky as i had to present my science fair first. If i had more time i would've made my board look better.

Finshed my science fair

I have finished my science fair and I will take it to school and present it.

Finshed testing

I have finally finished testing and have come up with my results. My next step will be to write up my hypothesis etc.

My Science Fair Topic

My science fair topic is going to be on
Do the more pulleys on a pulley affect the force of how it pulls?
