Gravity and Planet Formation Quiz

What is gravity?

• A force of repulsion between objects

• A force of attraction between any two objects

• A force that only affects planets

• A force that only exists on Earth

How does the mass of objects affect the gravitational force between them?

• The force decreases as mass increases

• The force is unaffected by mass

• The force increases as mass increases

• The force only depends on one object's mass

Which of the following best describes how planets form?

• They are created by explosions in space

• They are pulled together by gravity from dust and gas

• They are formed by the collision of stars

• They are made by assembling smaller planets

What is the primary force responsible for pulling dust and gas together to form planets?

• Magnetic force

• Electric force

• Nuclear force

• Gravitational force

How does the distance between two objects affect the gravitational force between them?

• The force increases as distance increases

• The force decreases as distance increases

• The force remains constant regardless of distance

• The force is only affected by mass, not distance

Which of the following is NOT a factor that affects the strength of gravitational force?

• Mass of the objects

• Distance between the objects

• Color of the objects

• Size of the objects

What is the relationship between an object's mass and its gravitational pull?

• Objects with less mass have a stronger gravitational pull

• Objects with more mass have a stronger gravitational pull

• All objects have the same gravitational pull regardless of mass

• Only planets have a gravitational pull

In the early stages of planet formation, what holds the dust and gas particles together?

• Magnetic fields

• Chemical bonds

• Gravitational attraction

• Electric charges

Which of the following best describes the process of planet formation?

• Sudden creation from nothing

• Gradual accumulation of matter over time

• Splitting of larger objects into smaller ones

• Rapid expansion of a single point

How does gravity affect the shape of planets as they form?

• It causes planets to become cube-shaped

• It has no effect on planet shape

• It pulls matter towards the center, creating a spherical shape

• It pushes matter outward, creating irregular shapes
