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






2. A wave that interferes with its own reflection so as to produce oscillations which stand still - rather than traveling down the length of the medium. Standing waves on a string with both ends tied down make up the harmonic series.






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






4. 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.






5. Any vector can be expressed as the sum of two mutually perpendicular component vectors. Usually - but not always - these components are multiples of the basis vectors - and ; that is - vectors along the x-axis and y-axis. We define these two vectors






6. A unit vector is a vector with length 1.






7. The straight line that runs through the focal point and the vertex of a mirror or lens.






8. 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.

9. 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.






10. 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






11. An image created by a mirror or lens in such a way that light does not actually come from where the image appears to be.






12. 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.






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






14. A model for the atom developed in 1913 by Niels Bohr. According to this model - the electrons orbiting a nucleus can only orbit at certain particular radii. Excited electrons may jump to a more distant radii and then return to their ground state - em






15. The spectrum containing all the different kinds of electromagnetic waves - ranging in wavelength and frequency.






16. The ratio of the size of the image produced by a mirror or lens to the size of the original object. This number is negative if the image is upside-down.






17. A back-and-forth movement about an equilibrium position. Springs - pendulums - and other oscillators experience harmonic motion.






18. The force transmitted along a rope or cable.






19. 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.






20. The angle between a refracted ray and the line normal to the surface.






21. 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.






22. The path of each planet around the sun is an ellipse with the sun at one focus.

23. The force necessary to maintain a body in uniform circular motion. This force is always directed radially toward the center of the circle.






24. 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






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






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






27. Indicates how "bouncy" or "stiff" a spring is. More specifically - the spring constant - k - is the constant of proportionality between the restoring force exerted by the spring - and the spring's displacement from equilibrium. The greater the value






28. 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.






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






30. Energy associated with an object's position in space - or configuration in relation to other objects. This is a latent form of energy - where the amount of potential energy reflects the amount of energy that potentially could be released as kinetic e






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






32. A wavelength - given by = h/mv - which is associated with matter. Louis de Broglie proposed the idea that matter could be treated as waves in 1923 and applied this theory successfully to small particles like electrons.






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






34. A mirror that is curved such that its center is closer to the viewer than the edges - such as a doorknob. Convex mirrors reflect light away from a focal point.






35. A scale for measuring temperature - defined such that 0K is the lowest theoretical temperature a material can have. 273K = 0ºC.






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






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






38. An electromagnetic wave of very high frequency.






39. When two waves of slightly different frequencies interfere with one another - they produce a "beating" interference pattern that alternates between constructive (in-phase) and destructive (out-of-phase). In the case of sound waves - this sort of inte






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






41. A vector quantity defined as the product of the force acting on a body multiplied by the time interval over which the force is exerted.






42. An object is called radioactive if it undergoes radioactive decay.






43. Atoms of the same element may have different numbers of neutrons and therefore different masses. Atoms of the same element but with different numbers of neutrons are called isotopes of the same element.






44. 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.






45. The acceleration of a body experiencing uniform circular motion. This acceleration is always directed toward the center of the circle.






46. Heat transfer via electromagnetic waves.






47. A pendulum consists of a bob connected to a rod or rope. At small angles - a pendulum's motion approximates simple harmonic motion as it swings back and forth without friction.






48. A transfer of thermal energy. We don't speak about systems "having" heat - but about their "transferring" heat - much in the way that dynamical systems don't "have" work - but rather "do" work.






49. A device made of two coils - which converts current of one voltage into current of another voltage. In a step-up transformer - the primary coil has fewer turns than the secondary - thus increasing the voltage. In a step-down transformer - the seconda






50. Waves produced by a source that is moving with respect to the observer will seem to have a higher frequency and smaller wavelength if the motion is towards the observer - and a lower frequency and longer wavelength if the motion is away from the obse
