Unit 5.2: Gravity and the Solar System

Front

What is the measure of the amount of matter in an object called?

Back

Mass

Front

What is the force of attraction between objects due to their masses?

Back

Gravity

Front

How does gravity change with distance between two objects?

Back

Gravity decreases as the distance between the objects increases.

Front

In the Earth-moon system, what does the tension on the chain represent in the hammer throw analogy?

Back

The gravitational force acting between the Earth and the moon.

Front

What is the term for a rotating cloud of gas and dust from which the sun and planets formed?

Back

Solar nebula

Front

What is the path that a body follows as it travels around another body in space called?

Back

Orbit

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with greater mass.

Front

What is the formula for calculating gravitational force between two objects?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two objects.

Front

What role does gravity play in the formation of planets?

Back

Gravity pulls together gas and dust to form planets from the solar nebula.

Front

What is the significance of orbits in the solar system?

Back

Orbits determine the paths of celestial bodies, including planets, moons, and satellites.
