Forces

We tested the affects of air resistance by making different sized parachutes and releasing them. Each group made a parachute of a different size, and we found that the largest one took the longest to fall because it had a larger surface area and created more air resistance.

We used Newton meters to measure the effect of gravity on different objects.

We used toy cars and ramps made from different materials to monitor how the amount of friction provided by some surfaces can affect the speed of the object.
