  1. 1: newtons law __- inertia, an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force
  2. 2: newtons law __ force=mass x acceleration
  3. 3: newtons law __for every action there is an equal and opposite reaction
  4. 9.8: near the earths surface, gravitational acceleration is ___m/s/s
  5. acceleration: rate of change in velocity

  22. forces: a paper on a desk has balanced _____ acting on it
  23. frame of reference: object or point from which motion is determined
  24. friction: force that opposes motion
  25. gravity: force of attraction between all objects in the universe
  26. hypothesis: prediction based on patterns and observations
  27. inertia: an objects tendency to resist a change in motion
  28. meter: length unit
  29. Momentum=: mass x velocity
  30. motion: change in position relative to a frame of reference

  32. projectile: any object that is thrown
  33. speed: distance traveled per unit of time
  34. straight: a _______ line means zero acceleration

  37. velocity: speed in a given direction
  38. volume: amount of space an object takes up
  39. weight: measure of the pull of gravity on an object
  40. weight=: mass x acceleration due to gravity
