Gravity Concepts Assessment

Why do we not feel the effects of gravity in space ?

• We are two close to the Earth

• The distance we are away from Earth

• The sun blocks the gravitational pull

• Then sun is too close

Which is a good example of why gravity is considered the weakest force

• Because the sun doesn't pull us off the Earth

• Because the moon affects the tides

• A magnet can pick up a paper clip while the Earth's gravity is pulling on it

• Becasue Jupiter is the largest planet in our solar system

Which best describes the difference between gravity and mass?

• The larger the mass the greater the gravitational pull

• The smaller the mass the greater the gravitational pull

• The greater the distance the smaller the gravitational pull

• The smaller the distance the greater the gravitationmal pull

Which are the two main factors that affect gravity?

• Speed and endurance

• Distance and speed

• Distance and length

• Distance and mass

Which statement best explains the way gravitational forces work?

• An attractive force which pulls objects towards one another

• A repulsive force that pushes objects away from each other

• All of the above

• None of the above

Do gravitational forces exist between all masses?

• Yes

• No

What are the four basic non-contact forces?

• Gravity, electromagnetism, strong and weak electricty

• Gravity, electromagnetism, strong and weak nuclear forces

• Strong and weak electricity, strong and weak gravity

• Electromagnetism, gravity, stong and weak subliminal forces

Which statement about gravity is the most correct?

• Gravity is not dependent on mass and distance

• Gravity is a contact force

• Gravity is not an important force

• Gravity is the weakest force but one of the most important

Which statement best describes the relationship between gravity and distance?

• The larger the distance the greater the gravitational pull

• The smaller the distance the greater the gravitational pull

• The larger the mass the greater the gravitational pull

• The smaller the mass the greater the gravitational pull

Which statement best describes why gravity is one of the most important forces?

• Gravity keeps us on the Earth

• Gravity helps explain that the Earth is spherical

• Gravity keeps the moon in orbit around us

• Gravity holds the entire universe together
