Gravity

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

• Model A
• Model B
• Both Model A and Model B (same gravity)

Do astronauts float away on the moon?

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

Where would you have more mass, on Earth or on the Moon?

• Earth
• Moon
• IS THE SAME, mass DOESN'T CHANGE
• In both Planets.

The moon's gravity is one sixth of Earth's gravity. If you weigh 100 Newtons on Earth, how much do you weigh on the moon?

• 1 newton

• 6 newtons

• 16.667 newtons

• 60 newtons

Why is the Earth's gravity stronger than the moon's gravity?

• The moon has no mass

• The Earth has a larger volume than the moon

• The Earth is more massive than the moon

• The moon is so far away from the Earth

According to Newton's Laws, what might happen to the Earth if its orbit moved farther away from the Sun?

• The Sun's gravitational pull on the Earth would increase

• The Earth's gravitational pull on the moon would increase

• The Sun's gravitational pull on the Earth would stay the same

• The Sun's gravitational pull on the Earth would decrease
