Question

Tides on Earth occur because the Moon's gravitational pull is not uniform across the planet. Which statement best explains this?

The Sun's gravity cancels out the Moon's gravity on the far side of Earth

The Moon's gravity only affects liquid water and not solid land

The Earth's rotation creates a force that pushes the oceans toward the Moon

The Moon pulls more strongly on the side of Earth closest to it than on the far side

Question

According to the relationship $W = mg$ , if an object is moved to a planet where the gravitational field strength $g$ is exactly half that of Earth's, which property of the object will also be halved?

Two masses $m_1$ and $m_2$ are separated by a distance . If mass is doubled and the distance is also doubled, what is the new gravitational force compared to the original force ?

For an object in a stable circular orbit around a planet, the gravitational force acts as a __________ force, changing the object's direction but not its speed.

True or False: In a gravitational field diagram for a spherical planet, the field lines are parallel to each other near the center of the planet.
