= __Our 2nd Experiment__ =

Our experiment was about rolling two balls down a ramp at the same time and look which one go further. We also changed the angle of the ramp/s and see what changed.

materials:

 * bouncy ball
 * ping pong ball
 * 2 ramps

aim:

 * We wanna know which one went further and why? Which Newton's law does it represent? What changes f we change the angle of the ramp/s?**

**Theory:**
We think that the bouncy ball is gonna go further because it has more mass. It represents the 2nd Newton's law because we can prove //more mass more acceleration, less mass less acceleration. Less mass, more force you need to put on, more force less mass you need to put on.// If we decrease the angle of the bouncy ball's ramp we got more possibilities that it stop next to the ping pong ball.

We could change...

 * angle of the ramps
 * mass
 * surface
 * size
 * shape

We could measure...

 * ramp
 * distance traveled from each ball
 * size
 * mass
 * acceleration

Process:

 * 1) Put the ramps next to each other, 30 degrees and in the same position.
 * 2) Roll down in one of the ramps, a bouncy ball and in the other ramp a ping pong ball.
 * 3) Measure the distance traveled of each ball.
 * 4) Put one ramp at 20 degrees and the other ramp leave it at 30.
 * 5) Roll the bouncy ball down the ramp in 20 degrees and the ping pong ball down the other.
 * 6) Measure distance traveled for each ball.
 * 7) Keep on changing the angle of the ramp(bouncy ball's ramp) and rolling down the balls
 * 8) Do a chart with different results (distance and mass)[[image:cn_2nd_expertiment_1.png width="621" height="465"]]
