Gravitational Force

If you double the mass of m2, by what factor will the gravitational force change?

• F/2
• 2F
• 4F
• F/4

If you decrease the mass of m1 by half, by what factor will the gravitational force change?

• F/2
• 2F
• 4F
• F/4

If you double the mass of m1 and triple the mass of m2, by what factor will the gravitational force change?

• F/5
• 5F
• 6F
• F/6

How are mass and gravitational force related?

• indirectly
• inversely
• inverse squarely
• directly

Every object in the universe attracts every other object.

• Law of Universal Gravitation
• Mass and Distance
• Inertia
• Newton's First Law of Motion

What does the strength of gravity between two objects depend upon?

• Mass & distance
• Mass & weight
• Gravity & inertia
• Inertia & mass

The force of gravity is also known as

• Mass
• Weight
• Distance
• Acceleration

Gravitational force between two massive spheres 

• is always an attraction
• depends on how massive they are
• depends inversely on the square of the distances between them
• all of the above

Force of gravity is inversely proportional to

• Mass
• Weight
• Distance
• Time

Double the distance between two objects

• 4 times greater gravity attraction
• 4 times weaker gravity attraction
• 2 times weaker gravity
• 2 times greater gravity
