Back

True.

Front

What are the outer planets of our solar system?

Back

The outer planets are Jupiter, Saturn, Uranus, and Neptune.

Front

What is the relationship between mass and gravity?

Back

The force of gravity increases with the mass of the objects involved.

Front

What is the effect of distance on gravitational force?

Back

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

Front

What is the formula for calculating gravitational force?

Back

The formula is 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

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

Front

What role does gravity play in the formation of planets?

Back

Gravity pulls together gas and dust in space to form planets.
