SAT Physics Formulas
Want to make your college applications look impressive? Take SAT Subject Tests in addition to the regular SAT.
Even though these tests will only be offered through the summer of 2021, and they focus on just one subject, they still offer a host of benefits for students who choose to take them:
- SAT Subject Tests highlight your strengths: Are you great at chemistry? Are you practically fluent in Spanish. These tests are your chance to show college admissions boards what you have to offer.
- SAT Subject Tests showcase your interests: If you want to major in biology and the schools on your list have competitive biology programs, taking the Subject Test for biology will show the school that you are serious about this course of study and qualified for admittance.
- SAT Subject Tests provide college credit: Some colleges and universities offer course credit for high Subject Tests scores, allowing you to save time and money as you further your education.
If you want your application to stand out, I highly recommend that you take the SAT Subject Tests for the subjects you know and enjoy the most.
If Physics is your strong suit, you can take the SAT Physics Subject Test. While this is a complicated subject and the test might seem daunting, there are strategies you can use to make the test more manageable.
One of the most valuable strategies for doing well on the SAT Physics Subject Test is to memorize important physics formulas in advance.
You only have 60 minutes to answer 75 multiple choice questions, and you will not be provided with a formula chart to help you out. The SAT Physics Subject Test also does not allow test takers to use a calculator on the exam.
If you don’t know the physics formulas that you will need to solve the questions on the test, or you are struggling to remember them in the heat of the moment, you are not going to earn a good score.
It’s critical that you memorize the most important formulas and use them on practice tests so that you are ready when it’s time for you to take the SAT Physics Subject Test.
Here are 11 key formulas you should know off the top of your head on test day:
Newton’s Law of Gravitation: Fg=the force of gravity; G= constant; m1,m2 =masses; r= distance of separation
The definition of acceleration: a= acceleration; v= change in velocity; t = change in time
Newton’s Second Law: F= force; m= mass; a= acceleration
The definition of momentum: p = momentum; m= mass; v= velocity
5. Potential energy
The definition of potential energy: PE = potential energy; m= mass g= acceleration; h= height
6. Centripetal acceleration
The centripetal acceleration of an object moving in a circle: ac= centripetal acceleration; v= velocity; r= radius
7. Spring force
Hooke’s Law: Fs=spring force; k= spring constant; x=compression
8. Electric force
Coulomb’s Law: F = electric force; k = constant; q1, q2 = charges; r = distance of separation
9. Circuit voltage
Ohm’s Law: V= voltage; I= current; R= resistance
10. Wave velocity
Formula for light and sound wave velocity: v = wave velocity; λ = wavelength; f = frequency
The definition of pressure: P= pressure; F= force; A= area
The SAT Physics Subject Test covers kinematics, dynamics, circuitry, energy, power, circular motion, torques, momentum, springs, gravity, waves and optics, electric fields, pressure, relativity, and thermodynamics.
In addition to the eleven key formulas provided above, you will want to memorize formulas that fall under these topics in order to ensure you’re prepared for the test.
