Samantha : egg car

Question

How can I protect an egg

as it rolls down a ramp and

into a wall?

Hypothesis

I think I can protect a plastic egg with 5 quarters in it from breaking as it runs off a ramp into a wall by using materials that are similar to the ones in a car.

Vocabulary words

Speed- Speed is the rate at which an object is able to move or operate.
Force- Force is the strength or energy as an attribute of physical action or movement.
Inertia- Inertia is the tendency of an object to continue doing what it is doing.
Acceleration- Acceleration is any change in direction of speed. Ex. , turning, slowing down, or speeding up.
Friction - Friction is the resistance that one surface or object encounters when moving over another.
Momentum- Momentum is the quantity of motion of a object.
Potential Energy- Potential energy is stored energy that is not moving.
Kinetic Energy- Kinetic energy is energy in motion, moving energy.

My Materials

The materials I used were duct tape to protect the egg,

and part of an egg carton.

I used lego wheels and a base made of legos.

Procedure

First I cut an egg holder out of a whole egg carton.

Next, I stuck two thin yellow lego pieces together

and put wheels on the bottom.

Next I put a green lego square on the top of that and

duct taped the egg carton piece on top.

Conclusion

My car was efficient because when it ran down the ramp and into the wall , it did not break and it kept the egg safe inside the car.
