Basic Physics Formula
Some basic but very important Physics formula is given below:
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 = dt
Where,
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 =v−ut
where,
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.
ρ=mV
Where,
ρ Density
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
Where,
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=Wt
Where,
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=mg
Where,
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=FA
Where,
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 = 12mv2
Where,
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
Where,
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= Vλ
Where,
f Frequency of the wave
V Velocity or wave speed
λ The wavelength of the wave
