Universal Gravitation & Uniform Circular Motion

Front

Gravitational force ___________________ rapidly as the distance between the objects increases.

Back

decreases

Front

Complete the following statement: The farther away two planets are the _______ the gravitational force between them.

Back

less

Front

If mass of a body moving in a circle with a uniform speed is doubled, its centripetal force becomes:

Back

Twice

Front

Two objects are attracted to each other with 36 N of gravitational force. What would the force between them be if the distance between them were doubled?

Back

9 N

Front

What happens to Gravitational force if I double both of the masses but don't change their distance?

Back

4x bigger

Front

What is the law of universal gravitation?

Back

Every point mass attracts every other point mass 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 centripetal force?

Back

The force required to keep an object moving in a circular path, directed towards the center of the circle.

Front

What happens to the gravitational force if the distance between two objects is halved?

Back

The gravitational force becomes four times greater.

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.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with an increase in mass.
