• is only on EARTH

What two things determine the gravity of an object?

• mass & weight

• mass & distance

• density & mass

• volume & distance

When will the forces of gravity between two objects be the GREATEST?

• when the masses of both objects are small and the objects are far apart

• when the masses of both objects are large and the objects are close together

• when the masses of both objects are small and the objects are close together

• when the masses of both objects are large and the objects are far apart

When will the gravity between two objects be the LEAST?

• when the masses of both objects is small and the objects are close together

• when the masses of both objects is small and the objects are far apart

• when the masses of both objects is large and the objects are close together

• when the masses of both objects is large and the objects are far apart

Which statement about gravity is true?

• gravity causes objects to push away from each other

• gravity only takes place between planets

• the moon doesn't have any gravity

Look at the picture.  Is the force of gravity on the boy a push or a pull? 

• Pull
• Push

As mass increases, what happens to gravitational force?

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

Which model has greater gravitational attraction (if any)

Which system has the greater gravitational attraction between the two objects (if any)?

• System A
• System B
• Same gravitational attraction fro System A and System B

Which System has the greater gravitational pull between the two objects?

• System 1
• System 2
• Same: there is no gravitational attraction between the two objects
