Forces and motion
What is "force equals mass times acceleration"?
Using a force to move an object a distance, in the same direction as the force is going
What is work?
A machine that will keep working forever without an external energy source.
What is a perpetual motion machine? (do they actually exist?)
Transverse and Longitudinal
What are the two forms of waves sound travels in?
The portion of electromagnetic radiation that is visible to us
What is visible light?
The rate or amount of changes in velocity (positive and negative)
What is acceleration?
Joules and calories
What are the two units of measuring energy?
Fahrenheit, Celsius, and Kelvin
What are the 3 temperature scales?
First human to ever travel faster than the speed of sound
What is (was) Chuck Yeager?
Photons
What are tiny packets of electromagnetic radiation?
The formula for calculating acceleration
What is Final Velocity minus Initial Velocity divided by Time equals acceleration?
The ability to do work
What is energy?
The theoretical point at which all molecular movement stops
What is absolute zero?
Zero decibels
What is the threshold of human hearing?
Something that light can do that sound cannot
(and "give you a sun burn" doesn't count)
What is travel through a vacuum? (empty space)
Displacement
Energy transformation
What is it called when energy is transformed into another form of energy?
Conduction, convection, radiation
What are the three ways thermal energy (heat) can travel?
Her hopeless love for this man who fell in love with his own image, made her fade away until all that was left of her was her voice.
(who were they?)
Who were Echo and Narcissus?
The theory (and branch of physics) that states that light can travel as a wave AND as a particle
What is quantum physics (aka quantum mechanics)?
Only time when the same results for calculating speed and for calculating velocity (with displacement) can be used (essentially the same formula too)
What is when an object doesn't change direction?
Simple machine that is classified according to where the load and effort are located with respect to the fulcrum.
What is a lever?
Chaos or disorder in the universe (and it is always increasing)
What is entropy?
Dolphins and bats use this to find food and navigate
What is echolocation?
Myopia and hyperopia
What are nearsightedness and farsightedness?
