# The Safety Car

## Question

Can I make a car to keep an egg safe when it hits a wall?

## Hypothesis

I think that an egg inside a car with padding or soft stuff will protect it very good.

## Background Knowledge

Speed- rapidity in moving, going, traveling ,proceeding, or performing

Force- physical power or strength possessed by a living being

Inertia- inertness, especially with regard to effort, motion, action, and the like

Acceleration- the act of accelerating; increase of speed or velocity

Friction- surface resistance to relative motion; as of a body sliding or rolling

Momentum- force or speed of of movement; impetus, as of a physical object or course of events

Potential Energy- the energy of a still object getting ready to move

Kinetic Energy- energy of motion

## Procedure

First, I found a cardboard box. Then, I measured an egg. Next, I cut out my cars edges and the bottom of the car. Finally, I put two straws on the bottom of the car and little wood steaks in the straw and hot glued my car's sides and the wheels together.

## Conclusion

My speed of my car was not bad. I was kind of right about putting milk caps as my wheels. My car passed the crash stage, I tested it twice and stayed safe both times.
