UNIT 5 A+

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

The law of universal gravitation is credited to whom? 

• Einstein 
• Galileo
• Darwin
• Newton 

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)

• Model A
• Model B
• Both Model A and Model B (same gravity)

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

More mass equals:

• less gravity

• less distance

• more gravity

• more distance

Less mass equals:

• less gravity

• less distance

• more gravity

• more distance
