General Relativity-Assignment

Which two factors affect the force between two masses, according to the universal law of gravitation?

1 & 4 the masses of the objects the distance between the objects

Which provide evidence for the general theory of relativity? Check all that apply.

1, 4, & 5 gravitational lensing changes in Mercury's orbital path gravitational redshift

Which can be observed both on Earth and in an accelerating ship in space that is free from the effect of any gravitational field? Check all that apply.

2, 3, 4, & 5 apples falling from trees people's feet touching the ground sky divers moving toward the ground balls bending downward after being thrown

What is a wormhole, and how is it formed?

According to Einstein, a wormhole is made up of two types of holes: a black hole and a white hole. A black hole is a hole in space-time that an object, even light, can fall into but cannot escape from. A white hole is hypothetically a hole in space-time that objects can come out of but not fall into. The bridge between these two holes, or between these two space-times, is called a wormhole.

Which clock is moving more slowly?

B.

In which scenario does Einstein's theory apply, but not Newton's?

B. measuring how much energy light loses while it travels

Water is observed spilling to the floor in a spaceship. Describe the motion and location of the spaceship. Use the behavior of the water to justify your answer.

Based on the principle of equivalence, it is impossible to know the motion and location of the spaceship. The spaceship may be accelerating in space, or it may be stationary on Earth. In an accelerating spaceship, the water is stationary among the background of stars, and the spaceship floor rises to the water. On Earth, gravity causes the water to fall to the floor.

Compare Newton's and Einstein's views on the speed of light.

Newton believed that the speed of light changes and depends on the observer. Einstein, on the other hand, believed that the speed of light is constant and the same to all observers.

Can an object travel at the speed of light? Why or why not?

No object can travel at the speed of light. For an object to travel at the speed of light, the object would need infinite energy to increase its mass to infinity. There is no object that has infinite energy.

Complete the passage to describe Einstein's space-time. In a three-dimensional universe, the position of a spacecraft is defined by its . In a four-dimensional system, the spacecraft defines a line that represents through which the object passes.

Complete the passage to describe one of the features of Einstein's general theory of relativity. According to Einstein, space and time are and are parts of a whole universe that has four dimensions. Masses in the universe space-time, and the resulting shape of space-time causes .

relative curve gravity

Which planet would cause the most curvature in space-time?

D. Saturn

Which statement compares Newton's and Einstein's ideas on gravity?

C. Newton explained gravity as an attractive force between matter, while Einstein explained gravity as something caused by the curvature of space-time.

Why does gravitational redshift occur?

Gravitational redshift occurs because time slows down in a strong gravitational field. This causes the frequency of a wavelength of light to lower. Lower frequencies occur at the red end of the electromagnetic spectrum, so the light appears shifted to the red wavelengths.

According to Einstein's theory of relativity, what happens to the mass of an object as the object approaches the speed of light?

The mass of the object increases.
