all work, no play - Unit 7

After our long three day weekend, we got right back into physics by learning the kinematics of collisions. In this picture that mysteriously looks very similar to the one Mr. Blake took, our class is having a water balloon contest. This is to prove that objects have a limit to how much force they can stand. Like someone falling off of a 20 story building, "It's not the fall that kills them, it's the landing surface." What this quote is saying, is that when you are falling, your body increases velocity and the final force you land with is so great that your body can't handle it; therefore you die. Well in this fun activity we did at the end of class, we had to catch the water balloon in such a way that would cushion the water balloon so it wouldn't burst. We learned that if we increase the time where the balloon was caught, the less force would impact the egg. In the equation: delta P/change in time = avg. force, we see that force and time are inversely related, indicating that the more time it takes to catch, the less force will be exerted on that object.
