Exam 9: Gravity

Two objects move toward each other due to gravity. As the objects get closer and closer, the force between them

The difference between Newton's law as a proportion and an equation involves

There would be only one ocean tide per 24-hour day if the

Pluto is classified by as a

Earth is presently accelerating toward the Sun (centripetal acceleration). If the Sun collapsed into a black hole, this acceleration would

The best time for digging clams (when the low tide is extra low)is during the time of the

Which rocket would require more fuel?

In comparison with other fundamental forces, the universal gravitational constant G indicates that gravity is

The factor most directly responsible for making a black hole invisible is its

Half-way to the center of a planet of uniform density, your weight compared to that at the surface would be

On each given day and location, tides rise and fall at

A hollow spherical planet is inhabited by people who live inside it, where the gravitational field is zero. When a very massive spaceship lands on the planet's surface, inhabitants find that the gravitational field inside the planet is

Your weight is the force

If the mass of Earth somehow increased with no change in radius, your weight would

The force of gravity acts on all apples on an apple tree. Some apples are twice as far from the ground as others. For the same mass these twice-as-high apples have

When the distance between two stars decreases by one-third, the force between them

Tidal bulges on the Moon involve the concept of

Planets wobble in their orbits due to

For lunar tides to occur in the human body

According to Newton, when the distance between two interacting objects doubles, the gravitational force is
