yea ours broke

I thought our design was good. We had a crumple zone at the bottom along with feathers and crumpled tissue paper to lengthen the impact time with the cement. We had wings attached to the sides to slow down so the force is not as great. we also had the egg inside a little baggie filled with feathers. If the device fell like it is in the picture, we might of had a chance. During the fall the device was flipped over and the egg was smashed. We did not apply for wind variation and next time would make the device a lot different. overall the idea was good and should work in the future if it falls like the way we planned it.

Linear Momentum

This week in physics we learned about Linear Momentum on one axis. The si unit for momentum is kg x m/s. This is because mass times velocity is equal to momentum. Momentum in is equal to momentum out which means that everything must start and end with the same momentum. So a heavy person running slow will probably have the same momentum as a lighter person running faster than him. This is why in football, if your small, you should run as fast as you can into them. In this picture Kory has more momentum than the guy on the ground because even though their mass is the same, Kory has more velocity which means he has more momentum.

Momentum

Momentum is the product of mass and velocity. Momentum in = momentum out. This means that momentum can never be diminished. it always finishes what it starts out at. In this picture the kamehameha helmet has a momentum of zero. So, if there was a grenade under it, and it exploded into a million pieces, the momentum would still be zero. Zero momentum because if you add up all the pieces, they would equal out to zero.
