Design Process
100
A tool that helps lift weights, or loads, easier. The effort is applied on one part of the tool, which pivots around the fulcrum.
What is a lever?
100
The law of inertia. An object in motion, stays in motion. And an object at rest, stays at rest.
What is Newton's First Law?
100
a push or pull that acts on an object
What is a force?
100
This term describes the speed AND direction of an object
What is velocity?
100
This is the stage of the design process where you develop questions about a problem that needs to be solved.
What is "ask"
200
Can lift and move heavy weights with very little effort on our part. An example is a skateboard.
What is a wheel and axle?
200
Because of Newton's second law, F=m x a, we know that the the more massive an object is, the more/less force we need to move it. (choose one)
What is more?
200
the force that slows down or stops movement by a rubbing action
What is friction?
200
This is the measure of how hard it is to stop an object that's in motion.
What is momentum?
200
This stage is where you brainstorm different solutions to solve the problem.
What is "imagine"
300
A slanting surface connecting a lower level to a higher level. With these you trade distance for time.
What is an inclined plane?
300
When you swim you push the water one way, and you go forward. This an example Newton's third law which says:
Every action has an equal and opposite reaction.
300
The force of attraction between the mass of the Earth and any other object
What is gravity?
300
Energy that is stored or built up
What is potential energy?
300
This is the stage where you have a set design, figure out what materials you need, and how to build it.
What is "plan"
400
An object with at least one slanting side ending in a sharp edge, which cuts material apart, or can be used to lift objects.
What is a wedge?
400
If Ms. Welch crashes into you on the bumper cars, you will jerk forward much more than Ms. Welch will. This is because of which law?
What is Newton's 2nd Law?
400
The force of the particles in the air pushing against something to slow it down
What is air resistance?
400
Energy of an object in motion
What is kinetic energy
400
This is where you try out your product to see if it works
What is "test"
500
An inclined plane wrapped around a pole which holds things together or lifts materials.
What is a screw?
500
The reason you jerk forward in bumper cars after the car comes to a halt is because of this law:
What is Newton's 1st Law?
500
When there is a force that is stronger on one side than the other, which causes movement of an object.
What is unbalanced forces?
500
When you get on the highway you go from 30 miles per hour to 60 miles per hour. The term for this change in speed is:
What is acceleration?
500
This is after you test your product and realize what didn't work, you go back to fix it
What is "improve/redesign"
