Matter In Motion - Gravity:A Force of Attraction

What is the simplest way to find an object's center? spin it
What happens to the force of gravity between two objects as the distance between them increases? it decreases
What is the force of gravity directly related to? it is directly related to the amount of mass of the objects
What is all mass affected by? gravity
What does all matter have? mass
When is the gravitational pull greater between two objects? when they have greater masses
What is mass? a measure of the amount of matter
A student has a weight of 420 N on Earth. What is the student's weight on the moon? 70 N
What is the law of universal gravitation? gravitational force related to mass and distance
What can change with its location? an object weight
What is the force that pulls everything toward Earth's center? Earth's gravity
How much does a unit of mass weigh? a kilogram
What is the difference between mass and weight? Mass is the amount of matter in an object; weight is a measure of the gravitational force on an object
What must you know in order to determine the gravitational force between two objects? their masses and distance between them
Where would you weigh the most, on a boat, on a space shuttle, or on the moon? on a boat
What is weight? a measure of the gravitational force exerted on an object
What is gravity? a force attraction between objects that is due to their masses and the distance between the objects
What is center of mass? the point at which an object's total mass can be considered concentrated
What changes when gravitational force changes? weight
What would be your mass if you moved to Jupiter? unchanged
What would be your weight if you moved to Jupiter? changed
