Unit 5.2: Gravity and the Solar System

Front

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

Back

Orbit

Front

What is a natural or artificial body that revolves around a celestial body that is greater in mass?

Back

A satellite

Front

How does the moon's gravity compare to Earth's gravity?

Back

The moon's gravity is about 1/6th of Earth's gravity.

Front

How does Jupiter's gravity compare to Earth's gravity?

Back

Jupiter's gravity is more than twice as strong as Earth's.

Front

If an astronaut travels from Earth to the moon, how does their weight change due to gravity?

Back

Their weight will be less on the moon because of weaker gravity.

Front

If an astronaut travels from Earth to Jupiter, how does their weight change due to gravity?

Back

Their weight would be more on Jupiter because of stronger gravity.

Front

What term refers to the measure of the amount of matter in an object?

Back

Mass

Front

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

Back

The gravitational force acting between the Earth and the moon.

Front

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

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 masses.

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 × 10^-11 N(m/kg)^2.
