What is the force that attracts two bodies toward each other in the universe?
Gravity
True or False: Gravity is stronger on the Moon than on Earth.
False
Fill in the blank: The strength of gravity depends on the _____ of the objects and the distance between them.
mass
What law describes the gravitational attraction between two objects?
Newton’s Law of Universal Gravitation
Which planet in the solar system has the strongest gravitational pull?
Jupiter
Multiple Choice: What effect does gravity have on the orbits of planets? A) It causes them to spiral into the sun B) It keeps them in elliptical orbits C) It has no effect D) It causes them to move in straight lines
B) It keeps them in elliptical orbits
What is the term for the path that a celestial body follows as it moves through space?
Orbit
True or False: All objects in the solar system are affected by the Sun’s gravity.
True
What is the approximate strength of Earth’s gravity at its surface?
9.81 m/s²
Fill in the blank: The gravitational force between two objects decreases as the _____ between them increases.
distance
What phenomenon occurs when a massive object warps the fabric of space-time?
Gravitational lensing
Multiple Choice: Which of the following is NOT a planet in our solar system? A) Mars B) Venus C) Orion D) Saturn
C) Orion
What is the primary reason that planets stay in orbit around the Sun?
The gravitational pull of the Sun
True or False: The gravitational force is the same everywhere on Earth.
False
What is the term for the gravitational pull exerted by the Moon on Earth?
Lunar gravity
Fill in the blank: The gravitational force between two objects is directly proportional to the product of their _____ and inversely proportional to the square of the distance between them.
masses
What role does gravity play in the formation of stars?
It causes gas and dust to collapse into a dense core, leading to star formation.

B) Satellite
What effect does gravity have on time, according to Einstein’s theory of relativity?
Time moves slower in stronger gravitational fields.
True or False: The gravitational force between two objects is dependent on their shapes.
False
