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. An equation - PV = nRT - that relates the pressure - volume - temperature - and quantity of an ideal gas. An ideal gas is one that obeys the approximations laid out in the kinetic theory of gases.






2. In the Bohr model of the atom - the state in which an electron has the least energy and orbits closest to the nucleus.






3. Represented by R = 8.31 J/mol · K - the universal gas constant fits into the ideal gas law so as to relate temperature to the average kinetic energy of gas molecules.






4. 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.






5. A transverse traveling wave created by the oscillations of an electric field and a magnetic field. Electromagnetic waves travel at the speed of light - m/s. Examples include microwaves - X rays - and visible light.






6. The building blocks of all matter - quarks are the constituent parts of protons - neutrons - and mesons.






7. An object at rest remains at rest - unless acted upon by a net force. An object in motion remains in motion - unless acted upon by a net force.

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






9. The amount of heat necessary to transform a solid at a given temperature into a liquid of the same temperature - or the amount of heat needed to be removed from a liquid of a given temperature to transform it into a solid of the same temperature.






10. The name of an electron released from the surface of a metal due to the photoelectric effect.






11. The amplification of one wave by another - identical wave of the same sign. Two constructively interfering waves are said to be "in phase."






12. The energy of the molecules that make up an object. It is related to heat - which is the amount of energy transferred from one object to another object that is a different temperature.






13. The phenomenon of light bouncing off a surface - such as a mirror.






14. 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 -






15. The current induced in a circuit by a change in magnetic flux.






16. The series of standing waves supported by a string with both ends tied down. The first member of the series - called the fundamental - has two nodes at the ends and one anti-node in the middle. The higher harmonics are generated by placing an integra






17. The force involved in beta decay that changes a proton to a neutron and releases an electron and a neutrino.






18. The number of hydrogen atoms in one gram of hydrogen - equal to . When counting the number of molecules in a gas - it is often convenient to count them in moles.






19. 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.






20. The separation of different color light via refraction.






21. The property by which a charge moving in a magnetic field creates an electric field.






22. Another word for the frequency of a sound wave.






23. An almost massless particle of neutral charge that is released along with a beta particle in beta decay.






24. 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.






25. For a gas held at a constant temperature - pressure and volume are inversely proportional.

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






27. The dot product of the area and the magnetic field passing through it. Graphically - it is a measure of the number and length of magnetic field lines passing through that area. It is measured in Webers (Wb).






28. The study of the properties of visible light - i.e. - the portion of the electromagnetic spectrum with wavelengths between 360 and 780 nm (1 nm = m/s).






29. 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.






30. The tendency of an object to remain at a constant velocity - or its resistance to being accelerated. Newton's First Law is alternatively called the Law of Inertia because it describes this tendency.






31. The effect of force on rotational motion.






32. A measure of the average kinetic energy of the molecules in a system. Temperature is related to heat by the specific heat of a given substance.






33. The cosine of an angle in a right triangle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse.






34. 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.






35. A mirror that is curved such that its center is farther from the viewer than the edges - such as the front of a spoon. Concave mirrors reflect light through a focal point.






36. The reaction force of the ground - a table - etc. - when an object is placed upon it. The normal force is a direct consequence of Newton's Third Law: when an object is placed on the ground - the ground pushes back with the same force that it is pushe






37. A vector quantity defined as the rate of change of the velocity vector with time.






38. 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.






39. A neutrally charged particle that - along with protons - constitutes the nucleus of an atom.






40. The energy associated with the configuration of bodies attracted to each other by the gravitational force. It is a measure of the amount of work necessary to get the two bodies from a chosen point of reference to their present position. This point of






41. For a gas held at constant pressure - temperature and volume are directly proportional.

42. The standing wave with the lowest frequency that is supported by a string with both ends tied down is called the fundamental - or resonance - of the string. The wavelength of the fundamental is twice the length of the string - .






43. The square of the amplitude of a sound wave is called the sound's loudness - or volume.






44. Heat transfer via electromagnetic waves.






45. Occurs when every point in the rigid body moves in a circular path around a line called the axis of rotation.






46. Two oscillators that have the same frequency and amplitude - but reach their maximum displacements at different times - are said to have different phases. Similarly - two waves are in phase if their crests and troughs line up exactly - and they are o






47. Energy associated with the state of motion. The translational kinetic energy of an object is given by the equation .






48. Two materials are in thermal equilibrium if they are at the same temperature.






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






50. When objects collide - each object feels a force for a short amount of time. This force imparts an impulse - or changes the momentum of each of the colliding objects. The momentum of a system is conserved in all kinds of collisions. Kinetic energy is
