What is gravity?

• a force of attraction between objects that is due to their masses

• an unbalanced force that makes objects move in an elliptical path

• the rotating cloud of gas and dust from which the sun and planets formed

• the point in the orbit of a planet at which the planet is farthest from the sun

The distance between objects, along with the masses of the objects, affect the gravitational force between the objects. Which statement is true according to Newton’s law of universal gravitation?

• When the masses of objects increase, gravitational force decreases.

• When distance between objects increases, gravitational force decreases.

• When distance between objects decreases, gravitational force decreases.

• When the masses of objects decrease, the distance between objects decreases.

How is energy transported from the core to the surface of the sun by radiation and by convention.

• Radiation:Light particles bounce towards the convective zone. Convention: Hotter gases rise to the sun's surface, and then cooled and sink. This is a circular pattern.

• Radiation:Hotter gases rise to the sun's surface, and then cooled and sink. This is a circular pattern. Convention: Light particles bounce towards the convective zone

• The sun does not use radiation and convention. This is a trick question.

If Saturn has more mass than Earth, how would this affect your weight on Saturn?

• I will weigh more on Saturn

• I will weigh less on Saturn

• My weight will stay the same

• I will have no weight at all

A pattern or event in nature that is always true is what 

• scientific law 

• scientific theory

• hypothesis 

• controlled experiment 

Why is it important to perform multiple trials during an experiment? 

• It makes sure your results are more accurate 

• It fixes errors from the experiment 

• It allows you to keep track of your materials 

• It is not important to have multiple trials
