Universal Law of Gravitation

Question 1

Which best contrasts Newton’s and Einstein’s ideas?

Revolt · Accepted Answer

Newton believed that mass tells gravity how much force to exert. Einstein believed that mass tells space-time how to curve.

Question 2

The behavior of which objects are better explained by Einstein’s general theory of relativity than Newton’s universal law of gravitation?

Revolt · Accepted Answer

objects moving at near the speed of light

Question 3

An astronaut compares the time passing on a watch worn while on a mission orbiting Earth with an identical watch on Earth. The astronaut’s watch shows that two hours have passed.What would the watch on Earth show?

Revolt · Accepted Answer

Less than two hours have passed because time passes more slowly in areas with stronger gravitational fields.

Question 4

[BLANK]

Revolt · Accepted Answer

speed of light

Question 5

Masses in the universe curve space-time.What does the resulting shape of space-time cause?

Revolt · Accepted Answer

gravity

Question 6

Which best explains a difference between Einstein’s general theory of relativity and his special theory of relativity?

Revolt · Accepted Answer

His general theory includes uniform and accelerated motion, but his special theory applies only to uniform motion.

Question 7

Which of these occur as part of gravitational redshift? Check all that apply.

Revolt · Accepted Answer

wavelength of light lengthens; frequency of light decreases; light observed on Earth appears more red

Question 8

A scientist obtains images of a particular star, which appears as four separate stars.Which phenomenon causes the star to appear this way?

Revolt · Accepted Answer

gravitational lensing

Question 9

What did both Newton and Einstein believe directly affects gravity?

Revolt · Accepted Answer

mass of objects
