Across
  1. 2. One of the four fundamental physical forces. Is only attractive, never repulsive. Arises between particles of matter.
  2. 3. The force acting on a mass due to gravity. Measured in Newtons.
  3. 6. A physical measurement of the resistance of a body to acceleration. Measured in kilograms in the Metric System.
  4. 10. One of the four fundamental physical forces. The unification of electric and magnetic forces.
  5. 11. of the four fundamental physical forces. Binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between all particles containing quarks.
  6. 13. A region in space where each point is affected by a force. There are four fundamental field forces.
  7. 16. Statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. These often, at least originally, lacked a theoretical explanation.
  8. 18. A measure of how likely it is for an object to topple over when pushed or moved.
  9. 19. The rate of an object in free fall on the surface of the Earth. Numerically equal to 9.8 m/s2.
  10. 21. The rate of change of velocity per unit of time. Force divided by mass.
  11. 22. Part of one of the four fundamental physical forces. Can be attractive or repulsive. Arises between electrically charged particles because of their motion.
  12. 23. A physical measurement of a substance that is measured in kilograms in the Metric System. There are two kinds: Inertial and Gravitational.
  13. 24. A physical measurement of a body as measured by its gravitational attraction for other bodies. Measured in kilograms in the Metric System.
Down
  1. 1. A fundamental law of physics that states that gravitational and inertial masses are of a similar nature, quantitatively identical, and apparently indistinguishable.
  2. 4. Part of one of the four fundamental physical forces. Can be attractive or repulsive. Arises between electrically charged particles.
  3. 5. The constant of proportionality in Newton’s law of universal gravity. Numerically equal to 6.67 x10-11 N2m2/kg2.
  4. 7. A group of ideas that explain a group of facts or phenomena, also called laws, in the natural world. These are repeatedly confirmed through experiment or observation.
  5. 8. These are everyday macroscopic manifestations of the electromagnetic force such as friction, the normal force, buoyancy, and tension.
  6. 9. One of the four fundamental physical forces. Causes some forms of radioactivity, governs the decay of unstable subatomic particles, and initiates the nuclear fusion reaction that fuels the Sun.
  7. 12. The same as the center of mass, but used when discussing balancing an object.
  8. 13. A push or a pull. Measured in Newtons in the Metric System.
  9. 14. A point in a body of matter where the total weight of the body may be thought to be concentrated. In a uniform gravitational field the center of gravity is the same as the centre of mass. In this case the term center of mass is preferred.
  10. 15. The resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. Measured in kilograms in the Metric System.
  11. 17. A point representing the mean position of the matter in a body or system.
  12. 20. theory that describes gravity.
