General Physics
What are Vernier calipers and a micrometer screw gauge?
The area under an acceleration-time graph.
What is change in velocity?
The value between two closest in-phase points on a wave is called this.
What is wavelength?
The reason why the sum of electric potential differences around any loop is zero.
What is conservation of energy?
When we subtract the proton number from the nucleon number we get the number of these
What are neutrons?
The shortcoming in an experiment with the improvement "Take more readings and plot a graph."
What is the improvement for: "Two data points are not enough to draw a valid conclusion about the relationship"?
These are the two conditions for an object to be in equilibrium
What happens when the net torque about any point is zero, and there is no resultant force on the object?
These waves are an example of resonance.
What are stationary/standing waves?
The property of a material that describes how easily charge flows through it.
What is conductivity/resistivity?
Rutherford was trying to prove this when he fired a beam of alpha particles through a gold sheet
What is the atom is mostly empty space with a tiny positively charged nucleus in the middle?
The SI unit for the spring constant
What is kg/s^2 ?
The area under this graph is the energy per unit volume stored.
What is a stress-strain graph?
The reasons for rainbow colours shining off a CD.
What is diffraction, reflection gratings and interference? (at least 2)
This device's I-V characteristic has a sharply increasing gradient at higher voltages.
What is a diode/LED?
This type of radiation disguises itself as an electron, it also can't go through aluminum or lead!
What is beta radiation?
The guy who named a model after a dessert.
Who is JJ Thompson?
The formula from which the conservation of momentum is derived.
What is Newton's second law (F=ma)?
The oscillation/disturbance of a wave is only in one direction.
What is polarization?
The magnitude of voltage that a potentiometer can measure is limited by this.
What is the voltage on the driver cell?
Fundamental particle that is neutral.
What is an electron/muon/tau antineutrino/neutrino?
The JR Maglev train in Japan, the the LHC (Large Hadron Collider) in Switzerland have this in common.
What is a superconductor?
Two things that have the same SI units, but only one is a vector, and they have completely unrelated definitions.
What is torque/moment and work?
The name to describe how high something sounds.
What is pitch?
The reason why neutral objects are attracted to charged objects.
What is polarization?
The SI unit for the activity of a radioactive substance
What is a Becquerel/Curie?
