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. An image created by a mirror or lens in such a way that light does not actually come from where the image appears to be.






2. A model for the atom developed in 1913 by Niels Bohr. According to this model - the electrons orbiting a nucleus can only orbit at certain particular radii. Excited electrons may jump to a more distant radii and then return to their ground state - em






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

4. When dealing with reflection or refraction - the incident ray is the ray of light before it strikes the reflecting or refracting surface.






5. An object cannot be cooled to absolute zero.






6. 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.

7. A rough approximation of how gases work - that is quite accurate in everyday conditions. According to the kinetic theory - gases are made up of tiny - round molecules that move about in accordance with Newton's Laws - and collide with one another and






8. The angle between a refracted ray and the line normal to the surface.






9. The property of a vector that distinguishes it from a scalar: while scalars have only a magnitude - vectors have both a magnitude and a direction. When graphing vectors in the xy-coordinate space - direction is usually given by the angle measured cou






10. Heat transfer via electromagnetic waves.






11. 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.






12. The two shorter sides of a right triangle that meet at the right angle.






13. 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






14. The points midway between nodes on a standing wave - where the oscillations are largest.






15. 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.






16. A particle - which consists of two protons and two neutrons. It is identical to the nucleus of a helium atom and is ejected by heavy particles undergoing alpha decay.






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






18. The disorder of a system.






19. The ray of light that is reflected from a mirror or other reflecting surface.






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






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






22. The ratio of the size of the image produced by a mirror or lens to the size of the original object. This number is negative if the image is upside-down.






23. The energy stored in a thermodynamic system.






24. 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.






25. A collision in which both kinetic energy and momentum are conserved.






26. A nuclear reaction that takes place only at very high temperatures. Two light atoms - often hydrogen - fuse together to form a larger single atom - releasing a vast amount of energy in the process.






27. The center of a mirror or lens.






28. The cosine of an angle in a right triangle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse.






29. 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.






30. The bending of light as it passes from one medium to another. Light refracts toward the normal when going from a less dense medium into a denser medium and away from the normal when going from a denser medium into a less dense medium.






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

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






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






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






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






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






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






38. A principle derived by Werner Heisenberg in 1927 that tells us that we can never know both the position and the momentum of a particle at any given time.






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






40. Heat transfer by molecular collisions.






41. 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.






42. The experience of being in free fall. If you are in a satellite - elevator - or other free-falling object - then you have a weight of zero Newtons relative to that object.






43. 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.






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






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






46. A law - || = - which states that the induced emf is the change in magnetic flux in a certain time.

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






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






50. 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.
