Collisions

= Collisions Experimentmedia type="file" key="CNnewtvideo.mov" width="300" height="300" = toc = = This experiment is to show the second law, F=mxa( Force= mass x acceleration).

**Aim: **
To track collisions between spheres of equal and unequal mass.

My group and I believe that if you roll down balls with two different masses, the ball with more mass will crash into the ball with less mass and the ball with less mass will fly/bounce away.
 * Theory: **

**Materials: **

 * Golf ball
 * ping pong ball
 * two ramps
 * Soapy water
 * Graph paper

**Progress: **

 * 1) Put the ramps up in front of each other in exacly the same angle. And leave some space in between and but the graph paper there.
 * 2) Put the two balls in the soapy water.
 * 3) Put them on the ramp and at the same time roll them down and see what happens after they collide.

**We could change: **

 * <span style="font-family: 'Comic Sans MS',cursive;">Mass
 * <span style="font-family: 'Comic Sans MS',cursive;">Distance
 * <span style="font-family: 'Comic Sans MS',cursive;">Surface
 * <span style="font-family: 'Comic Sans MS',cursive;">Steppness
 * <span style="font-family: 'Comic Sans MS',cursive;">friction
 * <span style="font-family: 'Comic Sans MS',cursive;">force

**<span style="font-family: 'Comic Sans MS',cursive; font-size: 14px; line-height: 20px;">We could measure or observe: **

 * <span style="font-family: 'Comic Sans MS',cursive;">Mass
 * <span style="font-family: 'Comic Sans MS',cursive;">Distance
 * <span style="font-family: 'Comic Sans MS',cursive;">Friction
 * <span style="font-family: 'Comic Sans MS',cursive;">force

<span style="font-family: 'Comic Sans MS',cursive;"> That experiment didn't work as well as we thought it would have, so we designed a new experiment.
 * <span style="font-family: 'Comic Sans MS',cursive;">Conclusion: **

<span style="font-family: 'Comic Sans MS',cursive;"> Here is how we planned it:

<span style="font-family: 'Comic Sans MS',cursive;"> Roll one ball at a time down(both balls have different masses) a ramp and see how far the ball goes.
 * <span style="font-family: 'Comic Sans MS',cursive;">Aim: **

**<span style="font-family: 'Comic Sans MS',cursive;">Theory: **
<span style="font-family: 'Comic Sans MS',cursive;"> My group and I believe that the ball with more mass will travel father than the ball with less mass no matter what the surface is.

**<span style="font-family: 'Comic Sans MS',cursive;">Materials: **

 * <span style="font-family: 'Comic Sans MS',cursive;">Golf ball
 * <span style="font-family: 'Comic Sans MS',cursive;">ping pong ball
 * <span style="font-family: 'Comic Sans MS',cursive;">1 ramp
 * <span style="font-family: 'Comic Sans MS',cursive;">maybe different types of surfaces


 * <span style="font-family: 'Comic Sans MS',cursive;">Progress: **
 * 1) <span style="font-family: 'Comic Sans MS',cursive;">Roll the golf ball down the ramp, be careful not to stop the ball once its rolling.
 * 2) <span style="font-family: 'Comic Sans MS',cursive;">Then roll the ping pong ball down the ramp and be careful not to stop the ball once its rolling.
 * 3) <span style="font-family: 'Comic Sans MS',cursive;">Then after the other ball has stopped, measure the distance between the two balls.
