Gravity

Any object in orbit is called a 

• plane
• satellite
• comet
• meteor 

The law of universal gravitation is credited to whom?

• Einstein
• Galileo
• Darwin
• Newton

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

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

Gravity attracts all objects toward one another.

• False
• True
• It depends

If Earth's mass was cut in half, what would happen to your weight?

• Increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• nothing, weight is not affected by gravitational force

As mass increases, what happens to gravitational force?

• increases
• decreases
• stays the same
• i don't know

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

• weight
• force
• mass
• newtons

A force that works against gravity and opposes motion between a surface in contact with the atmosphere.

• air resistance
• gravity
• momentum
• velocity

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
