Basic Physics Formulas Concept Formula Average Speed Formula It is used to calculate the average speed (S) of a moving body for the distance covered (D) as well as the time duration (T). S = d/t Acceleration Formula Acceleration refers to the rate of change in velocity to the change in time. It is denoted by symbol a. a =(v-u)/t Density Formula This formula depicts the denseness of material in a specific given area. ⍴ = m/V Power Formula The capacity to perform an activity is known as Energy. On the other hand, energy spent in carrying out an activity (work) for a particular period of time is termed as Power. P=W/t Newton’s Second Law Using the formula, the force can be expressed by the product of mass and acceleration of the body. F = ma
Weight Formula The formula measures the force with which an object falls due to gravity. W=mg Pressure Formula Pressure refers to the amount of force applied per unit area of the object.
P=F/A
Ohm’s Law Formula Ohm’s law states that the current passing through a conductor material is directly proportional to the potential difference between two endpoints of the conductor.
V= I × R
Kinetic Energy Formula Kinetic energy is the energy that is possessed by a body due to its state of motion. E = 1/2 mv² Frequency Formula Frequency refers to the revolutions completed per second or the number of wave cycles. F =v/λ Pendulum Formula This equation calculates how long the pendulum takes to swing back and forth in seconds T = 2π√Lg Fahrenheit Formula This is a conversion formula for temperature.
F = (9/5× °C) + 32
