Energy & Motion
The ability to do work or cause change.
What is energy?
When two objects bump into each other.
What is a collision?
The force that slows down a rolling egg racer when it rubs against the floor.
What is friction?
The very first step of the engineering design process where you figure out what you need to solve.
What is asking a question or defining the problem?
The fragile passenger you must safely transport in your Module 1 build.
What is an egg?
Energy of motion.
What is kinetic energy?
This happens to the shape or motion of objects when they collide with a heavy impact.
What is they change shape, bounce back, or slow down/stop?
A smooth tile surface usually creates this amount of friction compared to a rough carpet.
What is less friction?
A working model or early version of your egg racer used for testing.
What is a prototype?
The independent variable if you choose to change the size of the wheels on your racer.
What is the wheel size?
Stored energy waiting to be used, like a rubber band pulled back on an egg racer.
What is potential energy?
A safety feature designed to absorb energy and protect an egg during a crash.
What is a bumper or crumple zone?
This force pulls all objects down toward the center of the Earth.
What is gravity?
What you should do to your vehicle after your first egg racer test fails or breaks the egg.
What is redesign or modify?
An educated guess or prediction about which egg racer design will travel the farthest.
What is a hypothesis?
What happens to the speed of an egg racer when you apply a greater force?
What is it increases / goes faster?
If an egg racer hits a solid wall at a high speed, the force of the impact is...
What is greater / larger?
If your egg racer is sitting perfectly still on the ground, the forces acting on it are...
What is balanced?
The constraints in an engineering challenge refer to these.
What are limits or rules (like time, materials, or budget)?
When energy changes from one form to another (like potential energy turning into kinetic energy).
What is energy transfer or transformation?
The scientific term for a push or a pull.
What is a force?
Why engineers test multiple prototypes of egg racers before the final race.
What is to observe how different designs handle collisions and reduce damage?
Adding more mass (weight) to an egg racer changes how much of this is needed to get it moving.
What is force?
Recording distance, time, and whether the egg survived during a test run is an example of collecting this.
What is data or evidence?
If a vehicle doubles its speed, the kinetic energy involved in a potential crash becomes this many times greater.
What is four times greater (quadrupled)?
