What is a force?

• the PUSH or PULL on an object 
• The MOTION an object creates
• The objects HITTING one another
• Going REALLY FAST

The force of attraction between all matter.

• inertia
• friction
• net force
• 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

What states that "every object in the universe attracts every other object"?

• Law of Universal Gravitation
• Newton's First Law of Motion
• My mother
• Inertia & gravity

Force of gravity is directly proportional to

• Mass
• Weight
• Distance
• Time

If I double the distance between two objects, what happens to their gravitational Force?

• 4x bigger
• 4x smaller
• 2x bigger
• 2x smaller

If I double the mass of one object, but don't change anything else... WHat happens to the gravitational force between two objects?

• Doubles
• Quadruples
• Cut in Half
• 4x Smaller

Two asteroids exert a gravitational force, F, on each other. Some time later, the asteroids are now three times as far from each other as before. Which of the following represents the gravitational force at this distance? 

• F/3
• F/2
• F/6
• F/9

As the distance between objects increases...

• The smaller the force of gravity.

• The larger the force of gravity.

• Mass has no effect on the amount of gravity an object experiences.

The larger the mass of an object...

• The smaller the force of gravity.

• The larger the force of gravity.

• Mass has no effect on the amount of gravity an object experiences.
