# What are the 2 theory of relativity?

The special theory of relativity was based on two main postulates: first, that the speed of light is constant for all observers; and second, that observers moving at constant speeds should be subject to the same physical laws.

## Is there special relativity in AP Physics 2?

This year-long course provides an accelerated coverage of all topics required for the AP Physics 2 Exam: thermodynamics, fluids, waves, optics, special relativity, modern atomic physics, electricity, and magnetism.

## Is physics 2 AP hard?

The AP Physics 2 exam has a roughly average pass rate and perfect score rate compared to other AP exams. However, factors like your interest level in the subject and the teacher quality at your school are also important in determining the difficulty.

## What is Einstein’s special theory of relativity 2 points?

Einstein’s special theory of relativity states that the same laws of physics hold true in all inertial reference frames and that the speed of light is the same for all observers, even those moving with respect to one another.

## Is Physics 2 harder than physics 1?

Physics 2 is certainly harder than physics 1 because it is more abstract, has more irregular calculations, and has more challenging topics. Physics 1 is easier because it has topics that are easier to visualize and we are more familiar with.

## What is difference between AP Physics 1 and 2?

AP Physics 1 covers topics such as Newtonian mechanics, mechanical waves and the basics of electric circuits. AP Physics 2 continues with topics like electricity and magnetism, fluids and thermodynamics. They are equivalent to first-semester and second-semester college courses, respectively, in algebra-based physics.

## What is the easiest AP class?

• Physics C: Mechanics. 84.3% 41.6%
• Calculus BC. 81.6% 44.6%
• Spanish Literature. 75.1% 17.6%
• Physics C: Electricity and Magnetism. 74.4% 40.4%
• Physics 2. 73.3% 14.0%
• Computer Science Principles. 71.6% 10.9%
• Psychology. 71.3% 22.4%
• Computer Science A. 70.4% 25.6%

## Is AP Physics 2 harder than C?

Both AP Physics C courses are calculus-based, meaning you should have already taken calculus or concurrently be taking calculus while you take either AP Physics C course. This is the main factor that makes Physics C more challenging than Physics 1 and Physics 2.

## What is relativity in simple words?

Relativity is the word for how things only have importance in relation to other things. In physics, relativity refers to Einstein’s theory that time and space are not absolute. If you believe there are absolute, correct answers to everything, you probably don’t like relativity, which is the opposite of absolutism.

## How do you explain relativity?

Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

## What are the 3 laws of Einstein?

• Objects in motion or at rest remain in the same state unless an external force imposes change. This is also known as the concept of inertia.
• The force acting on an object is equal to the mass of the object multiplied by its acceleration.
• For every action, there is an equal and opposite reaction.

## Is the theory of relativity the same as E mc2?

E = mc. E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.

## Why is the theory of relativity important?

Formulated by Albert Einstein beginning in 1905, the theory of relativity explains the behavior of objects in space and time, and it can be used to predict things such as the existence of black holes, light bending due to gravity and the behavior of planets in their orbits.

## Is theory of relativity proven?

General relativity has also been confirmed many times, the classic experiments being the perihelion precession of Mercury’s orbit, the deflection of light by the Sun, and the gravitational redshift of light. Other tests confirmed the equivalence principle and frame dragging.

## Which is harder calculus or physics?

Answers and Replies. No, Physics is definitely harder than calculus.

## Does AP physics look good for college?

Both honors and AP courses are rigorous courses that most high schools weight more heavily on your transcript. AP courses, however, culminate in the AP Exam. Good AP scores show colleges you are ready to succeed at college-level work and can even earn you college credits.

## Whats harder AP chem or AP Physics?

Based on College Board pass rates, AP Physics 1 is more difficult than AP Chemistry. That said, AP Chemistry is not far behind — AP Physics 1 has a pass rate of about 52% while AP Chemistry has a pass rate of 56%.

## Which AP Physics is the hardest?

Physics 1 AP Physics 1 is considered one of the hardest AP classes, covering topics like Newtonian mechanics and electrical charge and force. Students also spend about 25% of their class time performing college-level lab experiments and writing reports.

## Is AP Physics 1 or C harder?

We all know that AP® Physics 1 is easier than AP® Physics C. We note that many of the AP® Physics C courses self-select for those motivated students or those with higher grades in Math. That is the reason for the ridiculously high rates for AP® Physics C as compared to AP® Physics 1.

## Do colleges give credit for AP Physics 1?

AP Physics 1 Score Information Since most colleges who do allow credit for the exam require a score of a 4 or 5, only about 21% of all test takers are likely to earn college credit. Be sure to consider this low success rate before deciding to take AP Physics 1 in high school.

## What AP exam has the lowest pass rate?

Despite a reputation as one of the most difficult AP classes, Physics 1 is also one of the most popular—137,229 students took it in 2021. Physics 1 has the lowest pass rate of any AP exam (42.1%) along with one of the lowest percentages of students scoring a 5 (just 6.9%).

## Is 5 APs too much?

You can definitely take 5 APs, but just make sure to stay on top of your work and spend a good amount of time studying to make sure you know the material.

## Is 4 APs too much?

Unless you’re applying to the most selective universities, 4 to 5 AP courses over your high school years is more than enough. For students applying to the most selective colleges, you might need 7–12.

## What is a 70 on the AP Exam?

Usually, a 70 to 75 percent out of 100 translates to a 5. However, there are some exams that are exceptions to this rule of thumb. The AP Grades that are reported to students, high schools, colleges, and universities in July are on AP’s five-point scale: 5: Extremely well qualified.

## What AP test has the highest pass rate?

Chinese,Calculus BC, Japanese, Drawing, and Physics C: Electricity and Magnetism are the AP tests with the highest average scores, but they are all known to be quite difficult.
