Foundations of Physics
This is the study of matter, energy, and how they interact.
What is physics?
This is what we call it when something changes position over time.
What is motion?
The ability to make something happen or move something.
What is energy?
The distance from one wave peak to the next.
What is wavelength?
This small particle has a negative charge.
What is an electron?
This approach includes asking questions, developing hypotheses, testing them, and analyzing results.
What is the scientific method?
This law says force is equal to mass times acceleration.
What is Newton's second law?
The energy an object has because it’s moving.
What is kinetic energy?
When two waves meet and combine, either making a bigger wave or canceling out.
What is interference?
The formula V = IR is also called this law.
What is Ohm’s Law?
This is the unit we use to measure force.
What is the newton?
This kind of force keeps an object moving in a circle.
What is centripetal force?
This rule says energy cannot be created or destroyed.
What is the conservation of energy?
The speed of light in a vacuum (hint: it’s very fast).
What is 3 x 10^8 meters per second?
The buildup of electric charge on a surface.
What is static electricity?
This area of physics studies motion and forces.
What is mechanics?
This law says that all objects pull on each other with gravity.
What is Newton's Law of Gravitation?
The amount of effort used to move something a certain distance.
What is work?
The change in sound pitch when something moves toward or away from you.
What is the Doppler effect?
The magnetic force depends on these three things: charge, speed, and field strength.
What are charge, velocity, and magnetic field strength?
This famous equation relates force, mass, and acceleration.
What is F = ma?
the amount of movement an object has, based on its mass and speed.
What is momentum?
A slanted surface that helps lift things more easily.
What is an inclined plane?
When white light spreads into colors as it passes through a prism.
What is dispersion?
This device makes electricity by spinning a coil in a magnetic field.
What is a generator?
