Gravitational Force

As mass decreases, gravitational force does what?

• Increases
• Decreases 
• Remains the same
• Changes

What is the measure of force of gravity on an object?

• Shape
• Height
• Weight
• Gravity

Which of the following is Newton's Law on Gravitation?

• F=Gm₁m₂/r
• F = Gm₁m₂/r²
• F = Gm₁m₂/2r
• F = m₁m₂/2r

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

As distance between two objects increases, the pull of gravity 

• Increases
• Decreases
• Stays the same

As distance separating the objects increases the force

• increases
• decreases
• stays the same

What happens to Gravitational force if I double both of the masses but don't change their distance?

• doubles
• half as big
• 4x bigger
• 4x smaller

When placed at equal distances apart, the greatest gravitational attraction will be between two

• skateboards

• bowling balls

• school buses

An object with more mass will exert greater gravitational force than an object with lesser mass.

• True

• False

Which of the following is true?

• m1 feels more force

• m2 feels more force

• they feel equal forces

• the net force is zero, so they feel no force
