Gravity

Gravity is the force objects put on each other because of their ______.

• Mass
• Friendliness
• Acceleration
• Speed

A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity
• Jupiter has less mass, and therefore more gravity
• Jupiter has more mass, and therefore less gravity
• Jupiter has less mass and therefore less gravity

If a person weighs 100 pounds on Earth, calculate how much that person would weight on Jupiter. (Jupiter has 3 times the amount of gravity that Earth does.)

• 33.3 pounds
• 100 pounds
• 300 pounds
• Not enough information given

• True
• Sometimes
• False
• Never

As distance between two objects increase the pull of gravity 

• Increases
• Decreases
• Stays the same

The force of gravity acting on an object is the object's ______.

• weight 
• friction 

The law of universal gravitation is credited to whom?

• Einstein
• Galileo
• Darwin
• Newton

The amount of matter in an object is 

• pressure
• weight
• mass
• force

Which of the following never changes no matter where in the universe?

• weight
• force
• mass
• pounds

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity
