Conclusions

   The purpose of our project was to obtain good pictures of the collision between two balls when dropped in succession. We wanted to find out if there was any deformation between the two balls (ball-ball deformation) when they collided with the copper-plate trigger during the course of the experiment. 

    During the experiment itself, we dropped two balls in succession onto a copper-plate contact trigger. When the first ball hit the contact trigger, the flash would discharge. This trigger was sometimes connected to a time delay circuit to alter the timing of the flash. The balls were dropped manually at a distance of around 1 m. We  used a Sony digital SLR camera to take the pictures. 

    During our experimentation we discovered that the contact trigger had a slight delay built into it. We dealt with this inherent delay by either not using the delay circuit or by altering capacitance and resistance within the circuit. We also found that the collisions between the two balls occurred at very high speeds which we found out.  The difficulty of acquiring a picture that captured the two balls in contact was much greater than we had previously expected. We found that it was very difficult to drop the two balls in immediate succession.  We found, through our experimentation, that only the bottom ball was deformed during the collision.
