According to Newton's law of gravitation, the Earth and the Moon are gravitationally attracted to each other. The more massive Earth attracts the Moon with...

the same force as the Moon attracts the Earth.

a stronger force than the Moon attracts the Earth.

a weaker force than the Moon attracts the Earth.

a force that is sometimes stronger and other times weaker than the Moon attracts the Earth.

The picture shows three objects gravitationally interacting with each other. Which object exerts the greatest force on object B?

A and C exert an equal force on B

The picture shows three objects gravitationally interacting with each other. Which object exerts the greatest force on object B?

A and C exert an equal force on B

The picture shows the gravitational field in the space surrounding the Earth. What is creating this gravitational field?

The universal gravitational constant.

The figure shows the gravitational field surrounding the Earth. Which of the following explains why the field lines point towards the Earth?

Gravity is an attractive force.

The force of gravity points towards the center of the Earth.

Falling bodies accelerate towards the center of the Earth.

The centripetal force on an object in circular motion is

in the same direction as the centripetal acceleration.

in the same direction as the tangential speed.

in the direction opposite the tangential speed.

in the direction opposite the centripetal acceleration.

In the figure, according to Kepler’s laws of planetary motion,

if Δt 1 = Δt 2 , then A 1 = A 2 .

if Δt 1 = Δt 2 , then the orbit is circular.

Newton’s law of universal gravitation

can be used to derive Kepler’s third law of planetary motion.

can be derived from Kepler’s laws of planetary motion.

can be used to disprove Kepler’s laws of planetary motion.

does not apply to Kepler’s laws of planetary motion.

Kepler's First Law states

Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

objects attract other objects with a force that is directly proportional to the product of their masses

the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

Kepler's Second Law states

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

objects attract other objects with a force that is directly proportional to the product of their masses

the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

Kepler's Third Law states

the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

objects attract other objects with a force that is directly proportional to the product of their masses

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

This is a statement of which scientific law? Object attract other objects with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them.

Newton's Law of Universal Gravitation

Which of the following most accurately describes the movement of the Earth around the Sun?

The Earth moves faster when it is closest to the Sun.

The Earth moves at a constant speed around the Sun.

The Earth moves slowest when it is closest to the Sun.

The Earth's speed varies dependent upon the phase of the moon.

Which of the following is the most accurate description of "escape velocity"?

Escape velocity is the velocity needed to get away from the Earth's gravitational force and not dependent upon the mass of the satellite.

Escape velocity is the velocity needed to get away from the Earth's gravitational force.

Escape velocity is the velocity needed to get away from the Earth's gravitational force and is dependent upon the mass of the satellite.

Escape velocity is the velocity needed to get away from the Earth's gravitational force and not dependent upon the mass of the satellite but is dependent upon the geometric structure of the launch vehicle.

State the definition of Gravitational field strength

Gravitational force per unit mass acting on a body at a point in a gravitational field

Gravitational force per unit time acting on a body at a point in a gravitational field

The force between two bodies of mass M and m is directly proportional to the product of their masses
