Gravity

Gravity from an object _____

• stops at it's surface
• stops after about 10,000 km
• stops at the edge of the solar system
• goes on forever

What is the SI unit used to measure force? 

• pounds 
• grams 
• newtons 
• kg/ m²

Gravity attracts all objects towards one another.

• False
• True
• It depends
• I don't care

Any object with mass is surrounded by a gravitational field.

• True
• Sometimes
• False
• Never

As distance between two objects increase the pull of gravity 

• Increases
• Decreases
• Stays the same

The force of gravity acting on an object is the object's ______.

• mass
• matter
• weight 
• terminal velocity 

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

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

• Pull
• Push
