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. A vector of magnitude 1 along one of the coordinate axes. Generally - we take the basis vectors to be and - the vectors of length 1 along the x- and y-axes - respectively.






2. The units of frequency - defined as inverse-seconds (1 Hz = 1 s-1). "Hertz" can be used interchangeably with "cycles per second."






3. A vector quantity - or vector - is an object possessing - and fully described by - a magnitude and a direction. Graphically a vector is depicted as an arrow with its magnitude given by the length of the arrow and its direction given by where the arro






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






5. Waves in which the medium moves in the direction perpendicular to the propagation of the wave. Waves on a stretched string - water waves - and electromagnetic waves are all examples of transverse waves.






6. The temperature at which a material will change phase from solid to liquid or liquid to solid.






7. 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.






8. 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






9. 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

10. 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






11. The center of an atom - where the protons and neutrons reside. Electrons then orbit this nucleus.






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






14. 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.






15. The amount of heat necessary for a material undergoing sublimation to make a phase change from gas to solid or solid to gas - without a change in temperature.






16. In reference to oscillation - amplitude is the maximum displacement of the oscillator from its equilibrium position. Amplitude tells how far an oscillator is swinging back and forth. In periodic motion - amplitude is the maximum displacement in each






17. A property of a metal - the minimum frequency of electromagnetic radiation that is necessary to release photoelectrons from that metal.






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






19. 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).






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






21. The points of maximum displacement along a wave. In traveling waves - the crests move in the direction of propagation of the wave. The crests of standing waves - also called anti-nodes - remain in one place.






22. 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






23. The unit of magnetic flux - equal to one T · m2.






24. The effect of force on rotational motion.






25. A collision in which the colliding particles stick together.






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






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






28. The temperature at which a material will change phase from liquid to gas or gas to liquid.






29. The line perpendicular to a surface. There is only one normal for any given surface.






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






31. The index of refraction n = c/v of a substance characterizes the speed of light in that substance - v. It also characterizes - by way of Snell's Law - the angle at which light refracts in that substance.






32. 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.






33. Objects that experience oscillatory or simple harmonic motion when distorted. Their motion is described by Hooke's Law.






34. States that the net work done on an object is equal to the object's change in kinetic energy.






35. The time - T - required for a rigid body to complete one revolution.






36. The longest side of a right triangle - opposite to the right angle.






37. A number - Z - associated with the number of protons in the nucleus of an atom. Every element can be defined in s of its atomic number - since every atom of a given element has the same number of protons.






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






39. The gravitational force exerted on a given mass.






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

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






42. 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






43. 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.






44. 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






45. The constant of proportionality in Newton's Law of Gravitation. It reflects the proportion of the gravitational force and - the product of two particles' masses divided by the square of the bodies' separation. N · m2/kg2.






46. 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






47. When an object is held in circular motion about a massive body - like a planet or a sun - due to the force of gravity - that object is said to be in orbit. Objects in orbit are in perpetual free fall - and so are therefore weightless.






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






49. 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.






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