Spring Gizmo

This Gizmo found the force exerted on the spring and how much it streches on varying strengths of springs when you put different weights on them.
Test on Spring One


I found that spring one was the weakest spring avalible, and would strech the most when weight was placed on the pan attached to the end of the spring.




Test on Spring Three


I found that spring three was stronger than was stronger than the other springs tested. Meaning it streched lass when weight was placed on the pan attached to the end of the spring. You could also use the line of best fit (as shown in picture) to predict other weights and the amout of stretch on the spring.

I observed that the higher tention springs will stretch less when weight is placed on them.

Shoot the Monkey






  1. I fired the cannon at a 30 degree angle with an initial velocity of 30 m/s to get the monkey to catch the banana in mid-air.

  2. To get a successfull shot you must predict where the monkey will be seconds after the shot is fired. You need to aim where the monkey will be.

As long at the cannon is pointed at the monkey or below him, he will most likely catch the banana because gravity is acting on both the banana and the monkey at -9.8m/s.
