Week 5- Balls and Ramps

-This week's lab involved making ramps to see how fast we could get a ball to roll down it. My group began with the Control to make sure we had something to refer back to once we started changing our variables. I will attach our data below, but out of all of the things we changed, the only thing that made it go faster was the angle of the ramp and the size of the ball. We found that the higher the angle of the ramp, the faster it went. We also found that the marble rolled the fastest out of all of the balls. 

But why is this? What theory makes this work? 

Newton's 1st Law of Motion                                                                                       - An object will not change its motion unless acted upon by an unbalanced force.   - An object at rest will stay at rest, an object in motion will stay in motion.               - Objects with greater mass have more inertia, meaning it takes more force to change their motion.

Newton's 2nd Law of Motion                                                                                     - The force acting on an object is equal to the mass of that object times its acceleration, F=M*A

Newton's 3rd Law of Motion                                                                                      - For every action, there is an equal and opposite reaction
