  1. 3. Any influence that tends to accelerate an object; a push or pull.
  2. 7. A measure of an object’s inertia; also a measure of the amount of matter in an object.
  3. 8. the law of inertia, or an object continues in its state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by a net force exerted upon it. Newton's _________ law
  4. 9. The property of an object or a system that enables it to do work.
  5. 10. Friction, or drag, that acts on something moving through air.
  6. 14. Energy of position, usually related to the relative position of two things.
  7. 15. Collision in which colliding objects rebound without lasting deformation or heat generation.
  8. 16. The energy of motion
  9. 18. When one body exerts a force on a 2nd body, the 2nd body exerts an equal and opposite force on the first. This is Newton's ____ Law.
  10. 19. The force that acts to resist the relative motion (or attempted) of objects or materials that are in contact.
  11. 20. pependicular force multiplied by the lever arm

  1. 1. an oscillation accompanied by a transfer of energy that travels through medium (space or mass)
  2. 2. is an effect that increases (or decreases) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.
  3. 4. Force per surface area where the force is normal to the surface.
  4. 5. The force on a body due to the gravitational attraction of another body.
  5. 6. the concepts of time and three-dimensional space regarded as fused in a four-dimensional continuum.
  6. 7. A collision in which the colliding objects become distorted and/or generate heat during the collision
  7. 8. the number of crests of a wave that move past a given point in a given unit of time.
  8. 11. The combination of all the forces that act on an object.
  9. 12. A diagram showing all the forces acting on an object.
  10. 13. The acceleration produced by a net force on a body is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the body. This is Newton's ___ Law.
  11. 17. For an object resting on a horizontal surface, the upward force that balances the weight of the object.
