  1. 1. Third Law s that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
  2. 4. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
  3. 5. Friction defined as a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement.
  4. 6. the strength and vitality required for sustained physical or mental activity.
  5. 9. the quantity of motion of a moving body, measured as a product of its mass and velocity.
  6. 10. Friction Static friction is a force that keeps an object at rest.
  7. 12. the resistance that one surface or object encounters when moving over another.
  8. 13. 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.

  1. 2. Second Law a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.
  2. 3. the speed of something in a given direction.
  3. 5. the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
  4. 7. a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
  5. 8. First Law Law of inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
  6. 11. the force exerted on the mass of a body by a gravitational field.
  7. 12. a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
  8. 14. the action or process of moving or being moved.
  9. 16. the systematic investigation into and study of materials and sources in order to establish facts and reach new conclusions.
  10. 17. the action of dividing or splitting something into two or more parts.
