What is a catalyst?

Substance that increases the rate of a chemical reaction without being consumed

200

What are 2 of the 4 most common bridges?

beam, arch, suspension, and truss bridge

200

Why do rockets have a round nose shape at the top?

To avoid heating up and minimize drag

200

What is Newtons 3rd law of motion?

For every action force, there is a opposite and equal reaction force

200

What is a volt?

It is the electrical potential, potential difference, and electromotive force

200

What is the first law of thermodynamics?

Energy can not be created or destroyed

300

What is a truss bridge?

A type of bridge that uses triangular structures to spread load

300

What is drag?

an aerodynamic force that opposes an objects motion in the air

300

What is the law of inertia?

An object in motion remains in motion

300

What is the purpose of grounding?

Provides a safe path for excess electricity to escape

300

Complete this reaction (Must be balanced as well):

What is shier force?

Unaligned forces acting on one part of a body in a specific direction, and another part of the body in the opposite direction.

400

What is Bernoulli's principle?

As the speed of fluid increases, its pressure decreases 

400

What is the difference between torque and force?

force is the push or pull used to move an object in a straight line, while torque is the amount of effort used to rotate an object.

400

What is the difference between tensile and compression strength?

Tensile strength is a objects resistance to being elongating and being pulled apart while compression strength is the capacity of a material to resist loads that reduce size

500

What are the 4 main forces acting on an aircraft in the air?

Thrust, drag, lift, and weight

500

What is a tachometer?

Device used to measure the rotational speed

500

What is Ohms law?

States the relationship between current, resistors, and voltage. Current is proportional to voltage and inversely proportional to current.
