  • Physics Formulas is a resource website for any physics students to learn and understand physics through the use of physics formulas. When possible, we will also show you how to derive certain physics formulas and prove theorems that would lead to common physics formulas.
  • In physics, formulas are used more often than in mathematics. Since in physics, it is all about the results of the physics experiments and the conclusions of physics projects, it is ok to use physics formulas to speed things up.
  • Physics equations are like physics formulas but much broader. Physics equations can be any math equations used in physics.
  • One way to calculate the average speed is to use math formula for speed. Speed formula is also known as average speed formula or speed distance formula or the formula for time distance and speed.
  • Below is a video showing how to calculate speed in physics. We are going to calculate average speed which is very useful in both math and physics.
  • Today we are going to discuss velocity and then the velocity formula. First of all, we are going to define what velocity is.
  • Below is a video explaining how to calculate velocity. Velocity is often used in physics and math in conjunction with speed and acceleration.
  • We have discussed speed and velocity, now we are going to discuss acceleration. First of all, we are going to define what an acceleration often used in physics is and then we are going to discuss the acceleration formula.
  • Newton's Laws or Newton's Laws of Motions were invented by the famous English mathematician, physicist, and astronomer Sir Isaac Newton. Among many other great discoveries, Sir Isaac Newton formulated three laws of motion known as Newton's three laws of motion which are still widely used today.
  • Newton's First Law or Newton's First Law of Motion is the first of Newton's Three laws of motion invented by Sir Isaac Newton, one of the greatest mathematician, physicist, and astronomer.
  • Newton's Second Law or Newton's second law of motion is probably the most famous of all of Newton's three laws of motion. Newton's second law of motion introduces one of the most famous mathematical or physics formula concerning mass, force and motion.
  • Newton's Third Law or Newton's third law of motion is the last of the Three Newton's Laws of Motion invented by famous and brilliant mathematician, physicist and astronomer, Sir Isaac Newton. The Three Newton's Laws of Motion shaped how we understand the world.
  • The key point to projectile motion in physics is to remember that gravity always acts downwards only. When dealing with projectile motion in physics,
  • From the graphical diagram of the projectile motion, the formulas of projectile motion are derived as follows. We have previously discussed the definition of projectile motion.
  • What is an electric current? An electric current is a flow of charge. In a metal or a wire, the electric current charge is carried by conduction of electrons which are not attached to any given fixed ion of the metal.
  • Logarithm functions are often used in math, physics and chemistry. Below are some logarithm formulas that you should memorize to help you solve math and physics problems involving logarithm.
  • Below are some important, basic list of formulas for physics. These formulas for physics are often used in school physics. They are both general physics formulas and basic physics formulas.
  • Simple Harmonic Motion in physics or SHM is defined as oscillating motion of an object about an fixed point such that the acceleration (a) of the object is given below.
  • The angular frequency is often denoted by w. The angular frequency is a constant of the motion. The angular frequency is most known in the simple harmonic motion equation (shm).
  • Below is the capacitor charge formula for a capacitor in a DC circuit. Before we discuss the capacitor charge formula, let's define what a capacitance (C) is.
  • In physics, the root mean square or rms value of an alternating current or potential difference is not the same as the root mean square used in math calculations.
  • Below is a formula for finding resistance often used in physics. We will also discuss Ohm's Laws. Before we discuss the formula for finding resistance, let's define what resistance is.
