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. Body diagram- Illustrates the forces acting on an object - drawn as vectors originating from the center of the object.






2. A constant - - not to be confused with wavelength - that defines the speed at which a radioactive element undergoes decay. The greater is - the faster the element decays.






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






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






5. 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.






6. In the graphical representation of vectors - the tip of the arrow is the pointy end.






7. The number of digits that have been accurately measured. When combining several measurements in a formula - the resulting calculation can only have as many significant digits as the measurement that has the smallest number of significant digits.






8. The center of a mirror or lens.






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






10. 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.

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






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






13. F = ma. The net force - F - acting on an object causes the object to accelerate - a. The magnitude of the acceleration is directly proportional to the net force on the object and inversely proportional to the mass - m - of the object.

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






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






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






17. 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.






18. The effect of force on rotational motion.






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






20. 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.






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






22. 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






23. If the net torque acting on a rigid body is zero - then the angular momentum of the body is constant or conserved.






24. A collision in which momentum is conserved but kinetic energy is not.






25. The mass difference between a nucleus and the sum of the masses of the constituent protons and neutrons.






26. A constant in the numerator of a formula.






27. The amplification of one wave by another - identical wave of the same sign. Two constructively interfering waves are said to be "in phase."






28. 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






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






30. An electromagnetic wave of very high frequency.






31. 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 .






32. 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.






33. A vector quantity defined as the rate of change of the displacement vector with time. It is to be contrasted with speed - which is a scalar quantity for which no direction is specified.






34. 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.






35. Heat transfer via electromagnetic waves.






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






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






38. 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.






39. 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.






40. The amount of error that's possible in a given measurement.






41. 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 - .






42. There are a few versions of this law. One is that heat flows spontaneously from hot to cold - but not in the reverse direction. Another is that there is no such thing as a 100% efficient heat engine. A third states that the entropy - or disorder - of






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






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






45. 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.






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






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






48. The time it takes a system to pass through one cycle of its repetitive motion. The period - T - is the inverse of the motion's frequency - f = 1/T.






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






50. 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.
