Gravitational Force, Mass and Distance Retest

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass. It depends on the masses of the objects and the distance between them.

Front

How does distance affect gravitational force?

Back

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

Front

What is weight?

Back

Weight is the force exerted by a planet on an object due to gravity.

Front

What are the two main variables that affect gravitational interaction?

Back

The two main variables are the masses of the objects and the distance between them.

Front

True or False: The gravitational force between two objects changes with the distance between them.

Back

True

Front

True or False: Two people sitting near each other in a classroom do not have a gravitational interaction between them.

Back

False. There is a gravitational interaction, but it is very small.

Front

What happens to gravitational force when two objects are closer together?

Back

The gravitational force increases when two objects are closer together.

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the formula for 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, a value used in calculating gravitational force.
