Crash Course Gravity

What does gravity do?

• Gravity pushes objects away from each other.
• Gravity has no effect on objects in space.
• Gravity only affects large celestial bodies.
• Gravity pulls objects towards each other and pulls humans down.

What would happen if gravity did not exist?

• Gravity would cause everything to stick together tightly.
• The universe would be perfectly balanced and stable.
• The universe would be chaotic, with no structure or life.

• Life would thrive in a weightless environment.

Scientifically, why did the apple fall and not fly away?

• The apple fell due to a strong wind pushing it down.
• The apple fell because of gravity.
• The apple fell because it was tired of hanging on the tree.
• The apple fell because it was too heavy to fly.

What does "up" and "down" really mean when speaking about gravity?

• "Up" is the direction objects will go and down is the direction objects will not go.

• "Up" is towards the Earth and "down" is away from the earth

• 'Up' and 'down' have no relation to gravity and are purely directional terms.
• "Up" is away from the Earth and "down" is towards the earth

What does the rubber band represent in the experiment?

• Air

• The Earth

• Space

• Gravity

On Earth, where does gravity pull objects?

• In a circular motion around the Earth
• Towards the center of the Earth
• Away from the Earth
• Towards the Moon

Which object has the greater force of gravity?

• Earth

• Moon

• Small Meteor

• Rocketship

The closer objects are towards each other, the weaker the pull of gravity, and the further apart objects are from each other, the stronger the pull of gravity,

• True

• False

Why did the hammer and feather fall at the same rate on the moon?

• The hammer and feather are made of different materials.
• The moon has a stronger gravitational pull than Earth.
• The hammer and feather fall at the same rate on the moon because there is no air resistance.
• The hammer is heavier than the feather.

Gravity is felt by all objects with mass equally.

• True

• False
