Each object circling the Sun travels along an ​ (a)   -shaped path called an orbit. This path is cause by ​ (b)   . Gravity is the attractive force, or pull, between objects that have ​ (c)   . The ​ (d)   an object's mass, the greater its graviational pull. Also, the closer objects are to one another, the ​ (e)   gravity's pull is between them.

• False

• Never

As distance between two objects increase the pull of gravity 

• Increases

• Decreases

• Stays the same

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

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

• weight and mass

• distance and weight

• mass and matter

• mass and distance

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

• the moon has less mass, and therefore less gravity

• the moon has more mass, and therefore less gravity

• the moon has less mass, and therefore more gravity

• the moon has more mass, and therefor more gravity
