  1. 3. a form of energy that causes a difference in temperature, or the perception of warmth.
  2. 5. the full length of a race.
  3. 6. the process of moving something from one place to another.
  4. 9. the moving of something from its place or position.
  5. 11. The act or process of changing position or place.
  6. 12. the branch of applied mathematics dealing with motion and forces producing motion.
  7. 15. Motion: a form of motion in which an object or particle is thrown near the earth's surface, and it moves along a curved path under the action of gravity only.
  8. 16. the path followed by a projectile flying or an object moving under the action of given forces.
  9. 19. the rate of change of velocity per unit of time.
  10. 21. the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.
  11. 23. used to show direction or position; a pointer.
  12. 24. the use of science in industry, engineering, etc., to invent useful things or to solve problems
  13. 25. a vector measurement of the rate and direction of motion or, in other terms, the rate and direction of the change in the position of an object.
  14. 26. A quantity, such as mass, length, or speed, that is completely specified by its magnitude and has no direction.

  1. 1. Quantities: Described by their magnitudes and appropriate units, and directions.
  2. 2. the rate at which someone or something is able to move or operate.
  3. 4. The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.
  4. 7. the branch of physical science concerned with the interrelationship and interconversion of different forms of energy and the behaviour of macroscopic systems in terms of certain basic quantities, such as pressure, temperature, etc.
  5. 8. is the set of physical phenomena associated with the presence and flow of electric charge.
  6. 10. Figures: Digits that show the number of units in a measurement expressed in decimal notation.
  7. 13. occurring or produced as a result or consequence of something.
  8. 14. the branch of mechanics concerned with the motion of bodies under the action of forces.
  9. 17. the scientific study of sight and the behavior of light, or the properties of transmission and deflection of other forms of radiation.
  10. 18. the size, length, or amount of something, as established by measuring.
  11. 20. Frame: A basis of a four-dimensional coordinate system in which the first coordinate is understood as a time coordinate, while the other three coordinates represent spatial dimensions.
  12. 22. a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
  13. 25. a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
  14. 26. vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air, and water.
