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






2. The five equations used to solve problems in kinematics in one dimension with uniform acceleration.






3. 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.






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






5. Heat transfer by molecular collisions.






6. For an oscillating spring - the restoring force exerted by the spring is directly proportional to the displacement. That is - the more the spring is displaced - the stronger the force that will pull toward the equilibrium position. This law is expres

7. The amount of heat of a material required to raise the temperature of either one kilogram or one gram of that material by one degree Celsius. Different units may be used depending on whether specific heat is measured in s of grams or kilograms - and






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






9. The movement of a rigid body's center of mass in space.






10. A nuclear reaction in which a high-energy neutron bombards a heavy - unstable atomic nucleus - causing it to split into two smaller nuclei - and releasing some neutrons and a vast amount of energy at the same time






11. 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.






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






13. 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.






14. A unit of measurement for energy on atomic levels. 1 eV = J.






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






16. To every action - there is an equal and opposite reaction. If an object A exerts a force on another object B - B will exert on A a force equal in magnitude and opposite in direction to the force exerted by A.

17. 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.






18. 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.






19. 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






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






21. Life- The amount of time it takes for one-half of a radioactive sample to decay.






22. Also called a converging lens - a lens that is thicker in the middle than at the edges. Convex lenses refract light through a focal point.






23. 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






24. The separation of different color light via refraction.






25. The model of the atom according to which negatively charged electrons orbit a positively charged nucleus. This model was developed by Ernest Rutherford in light of the results from his gold foil experiment.






26. 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.






27. When electromagnetic radiation shines upon a metal - the surface of the metal releases energized electrons. The way in which these electrons are released contradicts classical theories of electromagnetic radiation and supports the quantum view accord






28. 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.






29. 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.






30. A form of radioactive decay where a heavy element emits an alpha particle and some energy - thus transforming into a lighter - more stable - element.






31. Heat transfer via the mass movement of molecules.






32. A force caused by the roughness of two materials in contact - deformations in the materials - and a molecular attraction between the materials. Frictional forces are always parallel to the plane of contact between two surfaces and opposite the direct






33. In an interference or diffraction pattern - the places where there is the least light.






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






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






36. 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.






37. A law - || = - which states that the induced emf is the change in magnetic flux in a certain time.

38. 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 - .






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






40. 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






41. 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.






42. 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.






43. The number of cycles executed by a system in one second. Frequency is the inverse of period - f = 1/T. Frequency is measured in hertz - Hz.






44. A scale for measuring temperature - defined such that water freezes at 0ºC and boils at 100ºC. 0ºC = 273 K.






45. 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.






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






47. A sheet - film - or screen with a pattern of equally spaced slits. Typically the width of the slits and space between them is chosen to generate a particular diffraction pattern.
