SAT Subject Test: hysics

Subjects : sat, science, physics
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A measurement of a body's inertia - or resistance to being accelerated.






2. A wedge or a slide. The dynamics of objects sliding down inclined planes is a popular topic on SAT II Physics.






3. With spherical mirrors - the radius of the sphere of which the mirror is a part.






4. A positively charged particle that - along with the neutron - occupies the nucleus of the atom.






5. An object that retains its overall shape - meaning that the particles that make up the rigid body stay in the same position relative to one another.






6. The emf created by the motion of a charge through a magnetic field.






7. The cancellation of one wave by another wave that is exactly out of phase with the first. Despite the dramatic name of this phenomenon - nothing is "destroyed" by this interference—the two waves emerge intact once they have passed each other.






8. A transfer of thermal energy from one system to another.






9. The temperature at which a material will change phase from solid to liquid or liquid to solid.






10. A collision in which momentum is conserved but kinetic energy is not.






11. The distance between the focal point and the vertex of a mirror or lens. For concave mirrors and convex lenses - this number is positive. For convex mirrors and concave lenses - this number is negative.






12. A logorithmic unit for measuring the volume of sound - which is the square of the amplitude of sound waves.






13. The net change - - in a point's angular position - . It is a scalar quantity.






14. A principle derived by Werner Heisenberg in 1927 that tells us that we can never know both the position and the momentum of a particle at any given time.






15. The process by which a solid turns directly into gas - because it cannot exist as a liquid at a certain pressure.






16. A form of radioactivity where an excited atom releases a photon of gamma radiation - thereby returning to a lower energy state. The atomic structure itself does not change in the course of gamma radiation.






17. When an object is held in circular motion about a massive body - like a planet or a sun - due to the force of gravity - that object is said to be in orbit. Objects in orbit are in perpetual free fall - and so are therefore weightless.






18. The force that binds protons and neutrons together in the atomic nucleus.






19. The separation of different color light via refraction.






20. The force transmitted along a rope or cable.






21. Done when energy is transferred by a force. The work done by a force F in displacing an object by s is W = F · s.






22. A quantity that possesses a magnitude but not a direction. Mass and length are common examples.






23. A frequency - f - defined as the number of revolutions a rigid body makes in a given time interval. It is a scalar quantity commonly denoted in units of Hertz (Hz) or s-1.






24. The amount of energy that metal must absorb before it can release a photoelectron from the metal.






25. A unit for measuring angles; also called a "rad." 2p rad = 360º.






26. The substance that is displaced as a wave propagates through it. Air is the medium for sound waves - the string is the medium of transverse waves on a string - and water is the medium for ocean waves. Note that even if the waves in a given medium tra






27. The disorder of a system.






28. The principle by which the displacements from different waves traveling in the same medium add up. Superposition is the basis for interference.






29. A coefficient that tells how much a material will expand or contract lengthwise when it is heated or cooled.






30. The coefficient of kinetic friction - - for two materials is the constant of proportionality between the normal force and the force of kinetic friction. It is always a number between zero and one.






31. An experiment by Ernest Rutherford that proved for the first time that atoms have nuclei.






32. The velocity at any given instant in time. To be contrasted with average velocity - which is a measure of the change in displacement over a given time interval.






33. Two quantities are inversely proportional if an increase in one results in a proportional decrease in the other - and a decrease in one results in a proportional increase in the other. In a formula defining a certain quantity - those quantities to wh






34. For a heat engine - the ratio of work done by the engine to heat intake. Efficiency is never 100%.






35. The point of a mirror or lens where all light that runs parallel to the principal axis will be focused. Concave mirrors and convex lenses are designed to focus light into the focal point. Convex mirrors and concave lenses focus light away from the fo






36. An area of high air pressure that acts as the wave trough for sound waves. The spacing between successive rarefactions is the wavelength of sound - and the number of successive areas of rarefaction that arrive at the ear per second is the frequency -






37. When a solid - liquid - or gas changes into another phase of matter.






38. The force that causes simple harmonic motion. The restoring force is always directed toward an object's equilibrium position.






39. A wave on a string that is tied to a pole at one end will reflect back toward its source - producing a wave that is the mirror-image of the original and which travels in the opposite direction.






40. The bending of light as it passes from one medium to another. Light refracts toward the normal when going from a less dense medium into a denser medium and away from the normal when going from a denser medium into a less dense medium.






41. The motion of a body in a circular path with constant speed.






42. The time - T - required for a rigid body to complete one revolution.






43. States that the current induced in a circuit by a change in magnetic flux is in the direction that will oppose that change in flux. Using the right-hand rule - point your thumb in the opposite direction of the change in magnetic flux. The direction y

44. The line that every particle in the rotating rigid body circles about.






45. A machine that operates by taking heat from a hot place - doing some work with that heat - and then exhausting the rest of the heat into a cool place. The internal combustion engine of a car is an example of a heat engine.






46. A particle - which consists of two protons and two neutrons. It is identical to the nucleus of a helium atom and is ejected by heavy particles undergoing alpha decay.






47. A rough approximation of how gases work - that is quite accurate in everyday conditions. According to the kinetic theory - gases are made up of tiny - round molecules that move about in accordance with Newton's Laws - and collide with one another and






48. A scalar quantity. If an object is moved from point A to point B in space along path AB - the distance that the object has traveled is the length of the path AB. Distance is to be contrasted with displacement - which is simply a measure of the distan






49. A nuclear reaction that takes place only at very high temperatures. Two light atoms - often hydrogen - fuse together to form a larger single atom - releasing a vast amount of energy in the process.






50. The index of refraction n = c/v of a substance characterizes the speed of light in that substance - v. It also characterizes - by way of Snell's Law - the angle at which light refracts in that substance.
