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. Kinematics is the study and description of the motion of objects.






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






3. 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






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






5. The distance between successive wave crests - or troughs. Wavelength is measured in meters and is related to frequency and wave speed by = v/f.






6. For two given media - the smallest angle of incidence at which total internal reflection occurs.






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






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






9. The bending of light at the corners of objects or as it passes through narrow slits or apertures.






10. A property common to both vectors and scalars. In the graphical representation of a vector - the vector's magnitude is equal to the length of the arrow.






11. The state of a nonrotating object upon whom the net torque acting is zero.






12. A form of vector multiplication - where two vectors are multiplied to produce a scalar. The dot product of two vectors - A and B - is expressed by the equation A · B = AB cos .






13. The particles and energy released by the fission or fusion of one atom may trigger the fission or fusion of further atoms. In a chain reaction - fission or fusion is rapidly transferred to a large number of atoms - releasing tremendous amounts of ene






14. 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.






15. A form of radioactive decay where a heavy element ejects a beta particle and a neutrino - becoming a lighter element in the process.






16. The speed at which a wave crest or trough propagates. Note that this is not the speed at which the actual medium (like the stretched string or the air particles) moves.






17. A constant in the numerator of a formula.






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






19. A vector quantity - - that reflects the change of angular displacement with time - and is typically given in units of rad/s. To find the direction of the angular velocity vector - take your right hand and curl your fingers along the particle or body






20. The points on a standing wave where total destructive interference causes the medium to remain fixed at its equilibrium position.






21. 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.






22. 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.






23. The experience of being in free fall. If you are in a satellite - elevator - or other free-falling object - then you have a weight of zero Newtons relative to that object.






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






25. The mass number - A - is the sum of the number of protons and neutrons in a nucleus. It is very close to the weight of that nucleus in atomic mass units.






26. A class of elementary particle whose mass is between that of a proton and that of an electron. A common kind of meson is the pion.






27. A push or a pull that causes an object to accelerate.






28. The energy stored in a thermodynamic system.






29. The force between two surfaces moving relative to one another. The frictional force is parallel to the plane of contact between the two objects and in the opposite direction of the sliding object's motion.






30. The process by which a gas turns directly into a solid because it cannot exist as a liquid at certain pressures.






31. The effect of force on rotational motion.






32. A wave with wave crests that propagate down the length of the medium - in contrast to stationary standing waves. The velocity at which a crest propagates is called the wave speed.






33. Waves that oscillate in the same direction as the propagation of the wave. Sound is carried by longitudinal waves - since the air molecules move back and forth in the same direction the sound travels.






34. The points midway between nodes on a standing wave - where the oscillations are largest.






35. Linear momentum - p - commonly called "momentum" for short - is a vector quantity defined as the product of an object's mass - m - and its velocity - v.






36. The amount of heat needed to raise the temperature of one gram of water by one degree Celsius. 1 cal = 4.19 J.






37. 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.






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






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






40. If a line is drawn from the sun to the planet - then the area swept out by this line in a given time interval is constant.

41. 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.






42. An object that moves about a stable equilibrium point and experiences a restoring force that is directly proportional to the oscillator's displacement.






43. 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.






44. The amount of heat necessary to transform a liquid at a given temperature into a gas of the same temperature - or the amount of heat needed to be taken away from a gas of a given temperature to transform it into a liquid of the same temperature.






45. The stable position of a system where the net force acting on the object is zero.






46. An experiment in 1879 that showed that the speed of light is constant to all observers. Einstein used the results of this experiment as support for his theory of special relativity.






47. 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.






48. Heat transfer by molecular collisions.






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






50. 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.
