Have you ever wondered how gravity works? How these technologies are working? Physics gives you the reason for every why’s and how’s you have. Physics is all about understanding things and not about memorizing formulas and definitions with time. Till now, with Physics we’ve come so far and found the solution to many problems. We’ve to use our ability and resources and find out the solutions to problems that are still there. In this blog, we’ll notify you about 10+ physics formulas that will help you to score good marks in the examination.

10+ Important Basic Physics Formulas
1. Angular Speed Formula- It can be defined as the rate of change of angular displacement. It measures how fast the rotation of the central body changes with respect to time. The formula generally computes the total distance covered by the total time taken. It is denoted by ω.
Formula,
ω = Θ/t
Angular Speed = Total Distance Covered/ Total time taken
ω represents the angular speed in radians/ second
Θ represents the angle in the radian
t represents the total time taken
2. Displacement Formula- It is defined as the shortest distance between the initial point and the final point which prefers a straight line over curved paths. It is the change of a position from any point. It is denoted by s
Formula,
If the body is moving in two different directions then the shortcut result will be from the original path will be:
S = vt
S = ½ (u + v) t
S = ut + ½ at2
where,
s represents the displacement of the path
u represents the initial position of the path
v represents the final position of the path
a represents the acceleration
t represents the time travel
3. Distance Formula- It is defined as the total movement of an object from its initial position to the final position. It is denoted by d
Formula,
D = st
where,
D = Distance traveled
S = Speed of the moving object
T = Total time taken to cover the distance
4. Acceleration- A body is said to accelerate if there’s a change in velocity. In simple words, it means the rate of change of velocity with respect to the change of time taken. It is denoted by a
Formula,
a = (v — u)/t
where,
a represents the acceleration
v represents the final position
u represents the initial position
t represents the total time taken
5. Mass- It is the fundamental and the most basic property of all matters. It shows how much matter is present in an object. It is denoted by m.
Formula,
M = F/a
where,
F represents the force
m represents the mass of an object
a represents the acceleration
6. Weight- It is the measurement of the force acting on a body. It is denoted by w.
Formula,
W = mg
where,
w represents the weight
m represents the mass
and, g represents gravity.
7. Power- Energy that is spent in carrying out an activity or work is termed as Power. It is denoted by P.
Formula,
P = W/t
where,
P = power
w = work done
t = Total time taken
8. Work done by gravity– It is defined as the force that attracts a body towards any physical object having any mass. It is denoted by W.
Formula,
W= mgh
where,
w represents the work done
m represents the mass of the body
g represents the gravitational force
h represents the height
9. Gravity Formula- It is the force that occurs on all material objects in the universe. It is denoted by G.
Formula,
F= G (m1 m2 / r2 )
where,
G = Universal gravitational constant
m1 and m2 = masses of the two bodies
r = distance between the two masses
10. Force- It is an external agent which is able to change the motion of an object whether it’s in rest or moving. It is denoted by F.
Formula,
F= ma
where,
F represents the force on the object
m represents the mass of the body/object
a represents the acceleration
11. Torque Formula- It is defined as the turning effect of force on the axis of rotation. Torque is denoted by T.
Formula,
T= Fd
where,
T represents the Torque
F represents the force applied to the object
d represents the distance of force from the axis of rotation perpendicularly
12. Velocity Formula- The term velocity is defined as the rate of change of displacement. It is a vector quantity and the velocity of an object can be zero. It is denoted by V.
Formula,
v = 𝚫s/ 𝚫t
where,
V represents the velocity
𝚫s represents the displacement
𝚫t represents the change in time taken
13. Coulomb’s Law- The force between two charged bodies is directly proportion to the charges and inversely proportion to the square of the distance between them.
Formula,
F ∝ q1q2/d2
where,
F represents the force
d represents the distance between them
q1 and q2 represent the charged bodies
14. Ohm’s Law- According to Ohm’s law, the voltage is directly proportional to the current flowing in an electrical circuit. Where R is resistance constant.
Formula
V ∝ I
V = IR
Where,
V= Voltage in the circuit
I= current flowing in the circuit
R= resistance constant
