It was mainly finishing our lab and having a lab practical on the air tracks and the carts. We used a bullet to move the carts instead of just pushing it. The bullet made it go a little slower because it obviously had a lot less mass, which is less force and the bullet has less force than a hand pushing the carts.
We also just worked on our egg project during class. My partner is Dax. We are putting our egg inside plastic bottle. He cut the top off and on the bottom part I taped bubble wrap to the inside of the walls so that if the egg was to come free of the stuffing then it would have a somewhat soft landing. Inside the bubble wrap we're putting little styrofoam ball things, which should be soft enough to keep it from causing too much impact for the egg.

| This is a picture of my friend and I watching the fireworks. (The fireworks are in the back round) Fireworks have to do with momentum because first the firework has an initial velocity when it goes up into the air. When it reaches the top of it's path, it bursts into a million different pieces going all different directions. When it goes off in all different directions it's momentum changes. It's initial momentum when it's going up though is equal to the momentum of all the millions of pieces of fireworks added together because the momentum in is equal to the momentum out. :) |
