Grade 8 Oceanography and Hydrology
Why does the gravitational force of the Moon on Earth’s oceans is stronger than the gravitational force of the Sun?
  1. Moon’s air resistance keeps it from moving.
  2. Moon is smaller than the Sun.
  3. the Sun is made only of gas.
  4. Moon is closer to Earth than the Sun.
Grade 6 Forces and Motion
If Earth's mass doubled without changing it size, your weight would
  1. increase because gravitational force increases.
  2. decrease because gravitational force increases.
  3. increase because gravitational force decreases.
  4. not change because you are still on Earth.
Grade 8 Physics
Gravitational potential energy is the energy associated with                                                 .
  1. the motion of objects in space
  2. the gravitational force acting on an object

Grade 6 Forces and Motion
Which statement best states the relationship between mass and gravitational attraction?
  1. The less massive an object, the greater its gravitational pull.
  2. The masses of objects do not affect gravitational attraction.
  3. All objects have the same gravitational attraction on other objects.
  4. The more massive an object, the greater its gravitational pull.
Grade 5 The Moon
The tides are caused by gravitational pull on the oceans by
  1. the Sun and Moon.
