Universal Gravitation Practice Flashcard

Front

What happens to the gravitational force if both masses m1 and m2 are doubled?

Back

The gravitational force will quadruple (x4).

Front

If the mass of m2 is doubled, what happens to the gravitational force of attraction between m1 and m2?

Back

The gravitational force will double (x2).

Front

What does the big G represent in the Universal Gravitation equation?

Back

The Universal Gravitational Constant.

Front

What is the relationship between gravitational force and distance between two objects?

Back

As the distance increases, the gravitational force decreases.

Front

What did Newton discover about gravity?

Back

All objects exert a gravitational force on all other objects.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2.

Front

What is the value of the Universal Gravitational Constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

How does gravitational force change with distance?

Back

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

Front

What is the effect of increasing the distance on gravitational attraction?

Back

Increasing the distance decreases the gravitational attraction.

Front

What is the significance of gravitational force in the solar system?

Back

It keeps planets in orbit around the sun.
