Gravity & Balancing Torques Flashcard

Front

What happens to the gravitational force between two planets as the distance between them increases?

Back

The gravitational force decreases.

Front

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

Back

Front

What is the gravitational constant (G)?

Back

G = 6.673 x 10^-11 N(m/kg)^2.

Front

If Object 1 has a mass of 5 kg and Object 2 has a mass of 500 kg, what is the gravitational force between them when they are 25 m apart?

Back

2.688 x 10^-10 N.

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What is the gravitational force between a spacecraft of mass 1350 kg and the Earth (mass = 5.97 x 10^24 kg) when they are 12,800 km apart?

Back

3,282,470,703 N.

Front

What is the effect of distance on gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

Calculate the gravitational force between Earth (mass = 5.98 x 10^24 kg) and an object of mass 98 kg at a distance of 6.38 x 10^6 m from the center of the Earth.

Back

960.7425536 N.

Front

What is the relationship between gravitational force and distance?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of two objects.

Front

What is the significance of the law of universal gravitation?

Back

It describes the gravitational attraction between any two masses in the universe.
