Gravity

a measure of the gravitational force exerted on an object

• gravity

• weight

• mass

• velocity

a measure of the amount of matter in an object

• gravity

• weight

• mass

• velocity

a force of attraction between objects that is due to their masses and the distance between the objects

• gravity

• weight

• mass

• velocity

Which of these is true?

• Though all matter has mass, objects with small masses are unaffected by gravity

• All matter has mass; all mass is affected by gravity

• Only the Earth's gravity affects matter

• Only the Earth's and sun's gravity affects matter

The force of gravity

• is not related to the amount of mass of the objects

• is related to the amount of mass of the objects unless the mass is too small

• is related to the amount of mass of the objects but only indirectly

• is directly related to the amount of mass of the object

As the distance between two objects increase, the force of gravity between them

• decreases

• does not change

• increases only slightly

• increases greatly

Which of the following does NOT describe mass?

• remains constant

• is a measure of matter

• is a measure of gravitational force

• is measured in kilograms

Which of the following does NOT describe weight?

• changes as gravitational force changes

• is constant everywhere in the universe

• is a measure of gravitational force

• can be measured in newtons
