Gravity and Magnetism

Two factors effecting the magnitude of the force of gravity between 2 objects are...

• mass and distance 
• mass and matter
• distance and weight 
• weight and mass

As distance between two objects increase the pull of gravity 

• Increases
• Decreases
• Stays the same

The closer two objects are to each other

• the harder they will land
• have no gravitational force
• have a stronger gravitational force
• yep

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

Do astronauts float away on the moon?

• No, because Moon's gravity pulls them down.
• Yes, they float and can't even walk!

Which of these would have the strongest gravitational pull?

• A large, dense star

• A medium-sized planet

• A small moon

• A comet

Which of the following will not change in different gravitational fields?

• wieght
• force
• mass
• pounds

What would happen to your weight if Earth's mass was cut in half?

• increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• increase because gravitational force decreases
