  • unit for measuring weight? unit for measuring mass ?
    mass - Kg(kilograms); weight -N (newton)
  • arrange these objects based on which has the strongest gravitational pull. Earth, Moon, Jupiter, A large rock
    Jupiter- Earth- Moon- Large rock
  • The more matter something has, the less the force of its gravity. is this true or false?
    it is false because The more matter something has, the greater the force of its gravity.
  • if an object has a weight of 60N on earth, how much has it is going to have on the moon?
    10N. because the moon has 1/6 of the earth's gravitational force. so the weight of any object on the moon will be 1/6 the mass of that object on earth
  • which 5 have the highest gravitational force? why?
    Jupiter,Neptune, Saturn, earth, Venus . it has the highest gravitational force
  • who discovered gravity?
    Isaac Newton
  • what is gravity?
    Gravity is a force of attraction that pulls together all matter (anything you can physically touch).
  • what would happen to you if there there was no force of gravity on earth?
    you would be floating and fall off the surface of the earth
  • write the 8 planets in the solar system in order of their distance from the sun
    mercury, venus, earth, ,mars, Jupiter, Saturn, Uranus, Neptune
