SAT Subject Test: hysics

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 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.






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






3. 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.






4. 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.






5. The separation of different color light via refraction.






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






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






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






9. Heat transfer via electromagnetic waves.






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






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






12. A transfer of thermal energy from one system to another.






13. 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






14. The straight line that runs through the focal point and the vertex of a mirror or lens.






15. An electromagnetic wave of very high frequency.






16. 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.






17. A coefficient that tells how much a material will expand or contract lengthwise when it is heated or cooled.






18. 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.






19. 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.

20. An object is called radioactive if it undergoes radioactive decay.






21. An experiment by Ernest Rutherford that proved for the first time that atoms have nuclei.






22. 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.

23. A process that aligns a wave of light to oscillate in one dimension rather than two.






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. The tendency of an object to remain at a constant velocity - or its resistance to being accelerated. Newton's First Law is alternatively called the Law of Inertia because it describes this tendency.






26. The distance between successive wave crests - or troughs. Wavelength is measured in meters and is related to frequency and wave speed by = v/f.






27. 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.






28. A device that breaks incoming light down into spectral rays - so that one can see the exact wavelength constituents of the light.






29. A reference frame in which Newton's First Law is true. Two inertial reference frames move at a constant velocity relative to one another. According to the first postulate of Einstein's theory of special relativity - the laws of physics are the same i






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






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






32. A logorithmic unit for measuring the volume of sound - which is the square of the amplitude of sound waves.






33. 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).






34. 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).






35. Essentially a restatement of energy conservation - it states that the change in the internal energy of a system is equal to the heat added plus the work done on the system.






36. A sheet - film - or screen with a pattern of equally spaced slits. Typically the width of the slits and space between them is chosen to generate a particular diffraction pattern.






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






38. 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






39. 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.






40. 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.






41. 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.






42. 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.






43. 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.






44. 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






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






46. In the graphical representation of vectors - the tail of the arrow is the blunt end (the end without a point).






47. 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






48. 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.

49. For a reflected light ray - . In other words - a ray of light reflects of a surface in the same plane as the incident ray and the normal - and at an angle to the normal that is equal to the angle between the incident ray and the normal.






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