Astronomy
THIS is the source of energy that keeps a star burning.
What is nuclear fusion?
THIS is the rate of change of position, or the slope of the position graph.
What is VELOCITY?
This is the formula for Newton's Second Law of motion, also known as the Law of Acceleration.
What is Fnet=m * a?
THIS is the principle that energy cannot be created or destroyed, only changed or transferred.
THIS is the theory that describes the changing surface of the Earth, the matching of fossils and shapes of continents.
What is the theory of plate tectonics?
THIS is the key difference between stars that leads them to have different 'lives.'
What is their MASS?
When equal outside forces are applied to both a large and small mass THIS would be observed.
What is that the smaller mass would accelerate more?
Newton's 3rd Law says that " . . . for every action there is an equal and opposite reaction." In this phrase, the actions refer to THIS, the measurement of a push or a pull.
What are (action and reaction) FORCES?
Consider the electromagnetic spectrum. As the wavelength of the light INCREASES from blue to red, THIS is the observed change in the energy of each photon.
What is a decrease in energy?
THIS is the process that describes the transfer of heat and hot material through the Earth's mantle that interacts with the crust.
What is mantle convection (currents)?
The largest stars do THIS at the end of their lives, showering their galaxy with heavy elements.
What is go SUPERNOVA?
THIS is the rate of change of velocity. Also described as "slowing down, speeding up or turning."
What is ACCELERATION?
Newton's 2nd law says that an unbalanced for causes a mass to do THIS.
What is ACCELERATE?
What is sunlight?
Both the highest mountains and lowest ocean trenches are formed by THIS type of plate boundary.
What is a convergent boundary?
One can tell the temperature of the surface of a star by observing THIS feature.
What is its COLOR?
THIS is how one would describe the motion of an object with a leftward velocity and a rightward acceleration.
What is that the object is moving to the left and slowing down?
THIS is the name of the combination of forces that cause an acceleration.
What is the NET FORCE?
During a skydive, THIS is when the skydiver's potential energy is the higest.
The movement of rock and mantle is driven by gravity and uneven heating. On the surface of the Earth, THIS is why oceanic crust ALWAYS subducts under continental crust.
What is that the oceanic crust is more dense (or less buoyant)?
Far away galaxies all have their light spectra red shifting, indicating THIS about their motion.
What is that they are MOVING AWAY from us?
SURPRISE: Ask me a question using no more than 10 words on the topic of motion and force.
Answers vary. :]
THIS is the symbol for inertia one would find in Newton's 2nd law.
What is the letter 'm' for mass?
Write an example of when energy is NOT conserved for a simple system or a single object.
Answers vary. Object should be gaining or losing energy from its surrounding environment doing work on it.
THIS is what Mr. Flournoy studied in Australia while a student at Cal Poly.
What are reversals of the magnetic field?
