Mid-Term Review

  • centripetal acceleration- is towards the center of the curve
  • acceleration of gravity - is constant
  • gravity caused the formation of the Sun and the planets from a nebula
  • speed=distance/time
  • KE=1/2mv2
  • GPE= mgh
  • terrestrial planets have a solid iron core due their closeness to the Sun (gravity)
  • review phases of the moon material
