Universal Gravitation and Orbital Motion Review

Front

What is Universal Gravitation?

Back

Universal Gravitation is the law that states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

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 the centers of the two masses.

Front

How does distance affect gravitational force?

Back

Gravitational force is inversely related to the square of the distance between two objects. As distance increases, gravitational force decreases.

Front

What happens to your weight at the center of the Earth?

Back

Your weight becomes zero at the center of the Earth due to the equal gravitational pull from all directions.

Front

If an object is twice as far from a planet, how does the gravitational force change?

Back

The gravitational force is four times weaker when the object is twice as far from the planet.

Front

What is orbital motion?

Back

Orbital motion is the motion of an object in an orbit around a larger body due to the gravitational force acting between them.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the masses of the objects involved; as mass increases, gravitational force increases.

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the equation for gravitational force, allowing us to calculate the force between two masses.

Front

What is the effect of gravity on satellites in orbit?

Back

Gravity provides the necessary centripetal force that keeps satellites in orbit around a planet.

Front

How does the gravitational force change with distance in a two-satellite system?

Back

In a two-satellite system, if one satellite is twice as far from the planet, the gravitational force on it is one-fourth that of the closer satellite.
