Collisions

= __ ﻿ Collisions __ toc= Our experiment was about collisions. We supposed to roll down to balls from a ramp and see what happens after they collide. What we wanted to know is the acceleration and were did the balls go after they collide.

Aim:

 * We want to find out about 2 different things in our experiment. We suppose to find out about the acceleration and about what happens after they collide.**

**Theory:**
The theory of my group was that the 2 balls were going to collide and go in different directions/angles.

Materials:

 * Soapy water
 * 2 ramps
 * ping pong ball
 * golf ball
 * paper

**﻿Process:**
 * 1) Put the ramps face to face and put them exactly in the same angle. Also, leave a space between them and put the paper there.
 * 2) Wet the 2 balls with soapy water.
 * 3) Roll down the 2 balls at the same time and see what happens after they collide.

We could change...

 * surface
 * mass
 * object
 * friction
 * angle of the ramp

We could measure or observe...

 * angle of the ramp
 * surface
 * object
 * time
 * mass
 * force


 * We'd changed the mass and we'd measured the angle of the ramp.**

Balls that will collide...
(ball) ||
 * < More mass(ball) ||< Less mass
 * < 1.58 ||< 0.3 ||
 * < 0.86 ||< 0.3 ||
 * < 1.58 ||< 0.86 ||

Conclusion:
The golf ball was not stopping, as if nothing was on it's way. But the ping pong ball rolled in a different angle. We also tried another experiment with the same materials except for the paper and the soapy water. Below is the information about it.
