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






2. 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






3. 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






4. The points of maximum negative displacement along a wave. They are the opposite of wave crests.






5. In radioactive substances - the number of nuclei that decay per second. Activity - A - will be larger in large samples of radioactive material - since there will be more nuclei.






6. 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.






7. In a right triangle - the sine of a given angle is the length of the side opposite the angle divided by the length of the hypotenuse.






8. 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.






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

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






11. The force of gravity - F - between two particles of mass and - separated by a distance r - has a magnitude of - where G is the gravitational constant. The force is directed along the line joining the two particles.

12. 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.






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






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






15. Defined as the rate at which work is done - or the rate at which energy is transformed. P is measured in joules per second (J/s) - or watts (W).






16. 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 - .






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

18. The number - N - of neutrons in an atomic nucleus.






19. A means of defining the direction of the cross product vector. To define the direction of the vector - position your right hand so that your fingers point in the direction of A - and then curl them around so that they point in the direction of B. Th






20. The two shorter sides of a right triangle that meet at the right angle.






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






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






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






24. A small particle-like bundle of electromagnetic radiation.






25. 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.






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






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






28. Light such that all of the associated waves have the same wavelength and are in phase.






29. Heat transfer by molecular collisions.






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






31. The energy of a particle rotating around an axis.






32. A rigid body's resistance to being rotated. The moment of inertia for a single particle is MR2 - where M is the mass of the rigid body and R is the distance to the rotation axis. For rigid bodies - calculating the moment of inertia is more complicate






33. 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






34. 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






35. 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






36. 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.






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






38. The principle stating that for any isolated system - linear momentum is constant with time.






39. The property by which a changing current in one coil of wire induces an emf in another.






40. The application of kinematics to understand why objects move the way they do. More precisely - dynamics is the study of how forces cause motion.






41. A vector quantity - equal to the rate of change of the angular velocity vector with time. It is typically given in units of rad/s2.






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






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






44. 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.






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

46. 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 .






47. An area of high air pressure that acts as the wave crest for sound waves. The spacing between successive compressions is the wavelength of sound - and the number of successive areas of compression that arrive at the ear per second is the frequency -






48. The effect of force on rotational motion.






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. 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
