Exam 9: Gravity

Which pulls on the oceans of Earth with a greater force?

The universal gravitational constant G was first measured

According to Newton, the greater the masses of interacting objects, the

If a block is set sliding on a huge imaginary frictionless plane in contact with Earth's surface, it will NOT sustain a constant speed because

Wobbles in the path of Uranus led to the discovery of

The amount of gravitational force that acts on a space vehicle while in Earth orbit is

Which is most responsible for Earth's ocean tides?

If the Sun became twice as massive, your attraction to the Sun would double and your weight as measured on Earth would

How far must one travel to escape Earth's gravitational field?

If an object is placed exactly halfway between Earth and the Moon, it would fall toward the

Which produces a greater tidal effect in your body, the Moon or a 1-kg melon held at arm's length above your head?

If you drop a stone into a hole drilled all the way to the other side of Earth (neglect the molten core), the stone will

Suppose the Moon had twice the diameter but the same mass and same orbital distance from Earth. In that case, the high tides on Earth would be

An outcome of universal gravitation is that

If the Moon were covered with water, tidal effects caused by Earth would find the Moon with

Half-way to the center of a completely hollow planet with a thin uniform shell, your weight would be

If the Moon had twice as much mass and still orbits Earth at the same distance, ocean bulges on Earth would be

What is the force of gravity on a 500-N woman standing on Earth's surface?

All places on Earth would have high tides at the same instant if the

If the Sun were twice as massive
