What is the force of attraction that exists between all matter in the universe?
gravity
weight
mass
location
Who was the 17th century scientist to first explain gravity?
Henry Gillibrand
Francesco Redi
Robert Moray
Sir Isaac Newton
The Law of Gravitation states the force of attraction between any two objects depends on the masses of the objects and the distance between the objects.
True
False
What is the measure of the strength of the pull of gravity on an object?
Mass
Newton
Weight
Location
The mass of an object does not change with location. However an object's weight depends on its mass and its distance from the Earth's center.
True
False
The Law of Gravitation states that the force of gravity decreases as the distance form the Earth's center increases.
True
False
If the distance between the Earth's surface and its center of gravity is greater at the equator than at the North and South Poles, this difference in the distance means that your would weigh less at the equator than at the North or Sole Poles (0.3%).
True
False
