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 joule (J) is the unit of work and energy. A joule is 1 N · m or 1 kg · m2/s2.






2. A device made of two coils - which converts current of one voltage into current of another voltage. In a step-up transformer - the primary coil has fewer turns than the secondary - thus increasing the voltage. In a step-down transformer - the seconda






3. States that the current induced in a circuit by a change in magnetic flux is in the direction that will oppose that change in flux. Using the right-hand rule - point your thumb in the opposite direction of the change in magnetic flux. The direction y

4. The study of the properties of visible light - i.e. - the portion of the electromagnetic spectrum with wavelengths between 360 and 780 nm (1 nm = m/s).






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






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






7. 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.






8. An image created by a mirror or lens in such a way that light does actually come from where the image appears to be. If you place a screen in front of a real image - the image will be projected onto the screen.






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






10. A particle - identical to an electron. Beta particles are ejected from an atom in the process of beta decay.






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






12. A measurement of a body's inertia - or resistance to being accelerated.






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






14. The state of a nonrotating object upon whom the net torque acting is zero.






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






16. 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 .






17. 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






18. The speed at which a wave crest or trough propagates. Note that this is not the speed at which the actual medium (like the stretched string or the air particles) moves.






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






20. A measure of force per unit area. Pressure is measured in N/m2 or Pa.






21. 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.






22. 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






23. The amount heat necessary to cause a substance to undergo a phase transition.






24. 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






25. 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.






26. A negatively charged particle that orbits the nucleus of the atom.






27. A vector quantity - L - that is the rotational analogue of linear momentum. For a single particle - the angular momentum is the cross product of the particle's displacement from the axis of rotation and the particle's linear momentum - . For a rigid






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






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






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






31. 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.






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. The force between two surfaces moving relative to one another. The frictional force is parallel to the plane of contact between the two objects and in the opposite direction of the sliding object's motion.






34. A wedge or a slide. The dynamics of objects sliding down inclined planes is a popular topic on SAT II Physics.






35. The amount of heat needed to raise the temperature of one gram of water by one degree Celsius. 1 cal = 4.19 J.






36. The disorder of a system.






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






38. The position - of an object according to a co-ordinate system measured in s of the angle of the object from a certain origin axis. Conventionally - this origin axis is the positive x-axis.






39. A pulley is a simple machine that consists of a rope that slides around a disk or block.






40. 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.






41. 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.






42. 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.






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






44. 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.






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






46. 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






47. 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.






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






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






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