Gravitational Force Exerted by Earth

There is a gravitational force between you and your pencil. This gravitational force is very small because

• the masses are small

• it doesn’t need to be large

• the distance between the objects is to big

• it is a contact force

Mass is a measure of

• the amount of weight an object has

• the amount of space an object occupies

• the gravitational force on an object

• the amount of matter in an object

What statement best describes the relationship between mass and weight

• Mass and weight are proportional (10 g to .1 N)

• No relationship

• They are equal (10 g to 10 N)

• Mass is always less than weight
