List of Physics Formulas & Equations

Physics is the most basic subject of all sciences, and also it seems very harder to master. Basically learning physics is nothing but studying the basic laws which lead our universe. One can master in physics if they understand the theories thoroughly, and also they can easily identify the relation between the quantities or numbers by which they can form the formulas, derive it and learn simply.

Students who are looking for physics formulas can grab the list from this page and utilize them to revise daily and before your exams. While memorizing the physics formulas, first of all, try to understand what a formula says and means, and then what physics relation it outlined. If you comprehend the physics topics underlying those formulas, deriving & memorize them will be easy for you. So, use the list of physics equations available over here and solve the basic physics problems very easily & quickly.

1) Average Speed Formula:

The average speed is the average of speed of a moving body for the overall distance that it has covered.

S = \( \frac{d}{t} \)


S Average speed
d Total distance traveled
t Total time is taken

2) Acceleration Formula:

Acceleration is defined as the rate of change in velocity to the change in time. It is denoted by symbol a.

a =\( \frac{v-u}{t} \)


a Acceleration
v Final Velocity
u Initial Velocity
t Time taken

3) Density Formula:

The density of material shows the denseness of it in a specific given area.

\( \rho = \frac{m}{V} \)




m Mass of the body
V The volume of the body

 4) Newton’s Second Law:

According to Newton’s second law of motion, the force can be expressed by the product of mass and acceleration of the body.

F = m ×  a


F Force
m Mass of the body
a Acceleration in velocity available

5) Power Formula:

The capacity to do some work is termed as Energy. The Energy spent to do work in a unit amount of time is termed as Power.

P=\( \frac{W}{t} \)


P Power
W Work done
t Time taken

6) Weight Formula:

Weight is not anything but the force which an object experiences due to gravity.



W Weight
m Mass of the body
g Acceleration due to gravity

7) Pressure Formula:

The pressure is defined as the amount of force applied per unit area of the object.

P=\( \frac{F}{A} \)


P Pressure
F Force applied
A Total Area of the object

8) Kinetic Energy formula:

Kinetic energy is the energy that is possessed by a body due to its state of motion.

E = \( \frac{1}{2}mv^2 \)


E Kinetic Energy
m Mass of the body
v The velocity with which the body is traveling

 9) Ohms Law Formula:

Ohms law says that the current running through some conductor material is directly proportional to the potential difference between two endpoints of the conductor.

V= I × R


V Voltage measured in Volts
I Electric current flowing through the conductor in amperes.
R The resistance of the material in ohms.

10) Frequency Formula:

Frequency is the revolutions completed per second or as the number of wave cycles.

f= \( \frac{V}{\lambda} \)


f Frequency of the wave
V Velocity or wave speed



The wavelength of the wave

Final Words

This is the list of some of the important physics formulas that are used by all class students mostly to solve physics problems. Every branch of physics theory is replaced with countless formulas. If you grasp the underlying theory behind the formulas then physics will be easier for you. So, don’t just mug up the physics formulas mentioned here for the sake of exams, understand them, and relate them with every physics concept and be a creative student in your class.
