What would happen if the Earth did not have any gravity?
  • Life would cease to exist
  • All objects not anchored down on its surface would float
  • The moon would crash into the Earth
  • The lifespan of man and animals would drop sharply
This deals primarily with gravity.
  • Mass
  • Weight
  • Volume
  • Atmosphere
Why are people, animals and almost all objects attracted to the Earth?
  • It is where they were born or created so they have an attraction to remain in a place that is familiar to them
  • Because the moon has a smaller gravitational pull, people and animals would float away so they choose Earth instead
  • Because people and animals need oxygen, the Earth is the only source to get that oxygen to they are attracted to the Earth in order to find oxygen
  • Because the Earth is bigger than people, animals and objects on the Earth’s surface, they are attracted to the Earth through gravity
This is the amount of force that is exerted by larger objects over smaller objects.
  • Strong nuclear force
  • Weak nuclear force
  • Gravitational pull
  • Electromagnetic force
What is gravity?
  • It is the force that creates tidal waves
  • It is the relationship between the Earth and the moon
  • It is one of the four physical forces found in nature
  • It is the force that holds the Earth together
Why do your feet stay on the ground instead of floating?
  • Centrifugal force
  • Gravity
  • Volume and mass
  • Weight

  • Sun
  • Stars
  • Moon
  • Satellites
Who was the first scientist to really study and experiment with gravity and motion?
  • Sir Isaac Newton
  • Alex Haley
  • Aristotle
  • Plato
The closer the moon is to the Earth will result in what kind of ocean tides?
  • Flat
  • Lower
  • More
  • Higher
If you were to go to the moon, how would you feel?
