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 unit of force: 1 N is equivalent to a 1 kg · m/s2.






3. The process by which a solid turns directly into gas - because it cannot exist as a liquid at a certain pressure.






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






5. An object that moves about a stable equilibrium point and experiences a restoring force that is directly proportional to the oscillator's displacement.






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






7. 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






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






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






10. A mirror that is curved such that its center is farther from the viewer than the edges - such as the front of a spoon. Concave mirrors reflect light through a focal point.






11. 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.






12. A device that converts mechanical energy to electrical energy by rotating a coil in a magnetic field; sometimes called a "dynamo."






13. 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.






14. A body or set of bodies that we choose to analyze as a group.






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






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






17. 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.






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






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






20. 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






21. The point of a mirror or lens where all light that runs parallel to the principal axis will be focused. Concave mirrors and convex lenses are designed to focus light into the focal point. Convex mirrors and concave lenses focus light away from the fo






22. 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






23. 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.






24. A class of elementary particle whose mass is between that of a proton and that of an electron. A common kind of meson is the pion.






25. 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.






26. The angle between a reflected ray and the normal.






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






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






29. 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.






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






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

32. The velocity at any given instant in time. To be contrasted with average velocity - which is a measure of the change in displacement over a given time interval.






33. In a right triangle - the tangent of a given angle is the length of the side opposite the angle divided by the length of the side adjacent to the triangle.






34. An almost massless particle of neutral charge that is released along with a beta particle in beta decay.






35. An equation - PV = nRT - that relates the pressure - volume - temperature - and quantity of an ideal gas. An ideal gas is one that obeys the approximations laid out in the kinetic theory of gases.






36. The unit for measuring pressure. One Pascal is equal to one Newton per meter squared - 1 Pa = 1 N/m2.






37. 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.






38. 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.






39. An object at rest remains at rest - unless acted upon by a net force. An object in motion remains in motion - unless acted upon by a net force.

41. A form of vector multiplication - where two vectors are multiplied to produce a third vector. The cross product of two vectors - A and B - separated by an angle - - is - where is a unit vector perpendicular to both A and B. To deine which direction






42. 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 .






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






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






45. Waves carried by variations in air pressure. The speed of sound waves in air at room temperature and pressure is roughly 343 m/s.






46. 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.

47. The dot product of the area and the magnetic field passing through it. Graphically - it is a measure of the number and length of magnetic field lines passing through that area. It is measured in Webers (Wb).






48. The phenomenon by which light traveling from a high n to a low n material will reflect from the optical interface if the incident angle is greater than the critical angle.






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