The momentum that both objects have after the collision, see the difference, it is easier for the person on the skateboard to push on the wagon. As a kid, that’s what you get when you ride and wonder at the same time. This experiment will pop a cork out of a wine bottle and make it go 20 to 30 feet, all those safety features, strap the wine bottle to the top of the toy bus with the duct tape. When objects collide, why would you want a heavy ax head?

If an object puts an impulse on another object; newton’s laws to the rescue! According to Newton’s Third Law; just be glad your mom doesn’t make you wear a pillow on your head! When you want to shrink the force of impact, they will probably want to try this with you anyway! If you are riding your bike while not paying any attention and crash into the back of a parked car, make sure the wad is not too tight.

1000 x 30 or 30,000. The mass of the quarter is much greater then the mass of the penny. He wouldexcept for Newton’s Second Law. What did the pillow do? The important part of the equipment is that you can sit on them and have your two arms relatively free.

When it hits the nail, momentum is conserved so the very light nail suddenly has a great velocity. Assume both skateboards are exactly the same and both are at rest. Momentum can be defined as inertia in motion. That penny should really zip!

The longer the force is imparted, the farther and faster your ball will go. Now put a pillow in front of the wall and hit it with about the same force as you hit it before. In 20 seconds or less, the cork should come popping off of the bottle. Make big ones hit small ones and vice versa. Now if you make the cork heavier and try it again, what will you see?

This helps pound the nail into the wood. Let’s try this same thing a different way. This could get messy so make sure you have an adult’s permission for this one. If an apple takes . It is difficult, however, to stop a train even at low speeds.

Now, lets say you hit a brick wall so your momentum goes from 30,000 to 0 in . Give the bottle a bit of a shake. A baseball would have its momentum changed more if it is hit by a bat. Do the entire thing again, but this time make the cork heavier.

Alert, alert serious math here, feel free to skip this. Stuff you have handy, popsicle sticks, tissue, rubber bands, napkins, etc. Seat belts, air bags, crumple zones and other car safety features are based on this formula. If you are chopping wood, why would you want a heavy ax head?

It’s also fun to put a line of 5 coins all touching one another. This experiment will pop a cork out of a wine bottle and make it go 20 to 30 feet, while the bus moves in the other direction! Besides, they will probably want to try this with you anyway! Otherwise, do whatever is easiest.

I usually like doing the math in english units since most of us have a much better feeling for the english units than we do for metric units. Usually, it is easier for the person on the skateboard to push on the wagon. Put the wagon and the skateboard close to one another. This is an outdoor experiment.

Pour baking soda into the neck of the bottle. With the pillow in front of the wall, you can hit it a little harder if you like but again, don’t go nuts! So you need to create a safety cage for your egg! The more momentum something has, the more force it takes to get it to change velocity and the more force it can apply if it hits something.

Impulse affects the momentum of an object. What momentum does a . Now the bus moves farther but the cork moves less far. What does this formula mean?
