Gravity in the Solar System

Front

What keeps the Earth from crashing into the Sun?

Back

Earth's Inertia.

Front

What happens to a planet's speed as it gets closer to the Sun?

Back

The planet travels faster.

Front

What is gravity?

Back

The force that pulls things toward each other.

Front

What is the term for the amount of matter in an object?

Back

Mass.

Front

What keeps a planet moving on its path around the Sun?

Back

The balance between gravity and inertia.

Front

How does gravity affect the motion of planets in the solar system?

Back

Gravity pulls planets toward the Sun, keeping them in orbit.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What role does inertia play in planetary motion?

Back

Inertia keeps planets moving in a straight line unless acted upon by gravity.

Front

What is the effect of distance on gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is the formula for gravitational force?

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 their centers.
