The distance between objects, along with the masses of the objects, affect the gravitational force between the objects.

Which statement is true according to Newton’s law of universal gravitation?

• When the masses of objects increase, gravitational force decreases.

• When distance between objects increases, gravitational force decreases.

• When distance between objects decreases, gravitational force decreases.

• When the masses of objects decrease, the distance between objects decreases.

Which of these choices states Newton’s law of universal gravitation?

• As a planet moves around its orbit, the planet sweeps out equal areas in equal amounts of time.

• The orbit of a planet, or other body, around the sun is an ellipse, with the sun at one focus of the ellipse.

• The square of a planet’s orbital period is proportional to the cube of the planet’s mean distance from the sun.

• Gravitational force increases as the mass of an object increases or as the distance between two objects decreases.

Which statement best describes gravity acting as a centripetal force?

• A force that makes objects move in elliptical paths around the sun

• The point in an object’s orbit at which the object is closest to the sun

• The path that a body follows as it travels around another body in space

• The point in an object’s orbit at which the object is farthest from the sun
