The Kinematics Formula focuses on the motion of objects and includes key concepts such as displacement, velocity, acceleration, and time. These formulas are essential for understanding and analysing motion, which is an important part of the NEET Physics syllabus.

Average and Instantaneous Vel. and Accel.:
v̄ = Δr / Δt,  v = dr / dt
ā = Δv / Δt,  a = dv / dt

Motion in a straight line with constant a:
v = u + at,  s = ut + ½ at²,  v² − u² = 2as

Relative Velocity:

Reflection of Light Formula

Reflection of Light explains how light behaves when it strikes a surface. It includes important concepts like the laws of reflection, angle of incidence, and angle of reflection. These topics are highly important in optics and frequently appear in NEET Physics.

Laws of reflection:
(i) Incident ray, reflected ray, and normal lie in the same plane
(ii) ∠i = ∠r

Plane mirror:
(i) The image and the object are equidistant from the mirror
(ii) Virtual image of real object

Spherical Mirror:

1. Focal length f = R / 2

2. Mirror equation 1/v + 1/u = 1/f

3. Magnification m = −v/u

Specific Heat Capacity

The Specific Heat Capacity topic explains how much heat is needed to change the temperature of a substance. These formulas are important for understanding heat transfer and are commonly used in NEET Physics questions.

Specific heat:
s = Q / mΔT

Latent heat:

Relation between Cₚ and Cᵥ:
Cₚ − Cᵥ = R

Ratio of specific heats:
γ = Cₚ / Cᵥ

Relation between U and Cᵥ:
ΔU = nCᵥΔT

Specific heat of gas mixture:
Cᵥ = (n₁Cᵥ₁ + n₂Cᵥ₂) / (n₁ + n₂),  γ = (n₁Cₚ₁ + n₂Cₚ₂) / (n₁Cᵥ₁ + n₂Cᵥ₂)

Molar internal energy of an ideal gas:

Gravitation Formula

The Gravitation Formula describes the force acting between masses and includes important concepts from Newton’s law of gravitation. These formulas are essential for understanding planetary motion and are frequently asked in NEET Physics.

Gravitational force:
F = Gm₁m₂ / r²

Potential energy:
U = −GMm / r

Gravitational acceleration:
g = GM / R²

Variation of g with depth:
g_inside ≈ g (1 − 2h / R)

Variation of g with height:
g_outside ≈ g (1 − h / R)

Effect of non-spherical earth shape on g:
g at pole > g at equator (∵ Rₑ − Rₚ ≈ 21 km)

Effect of earth rotation on apparent weight:
mg′ = mg − mω²R cos²θ

Orbital velocity of satellite:
v₀ = √(GM / R)

Vectors Formula

The Vectors Formula covers quantities that have both magnitude and direction. These formulas are important for understanding vector operations and are widely used in solving NEET Physics problems.

Notation:
a⃗ = aₓ î + aᵧ ĵ + a_z k̂

Magnitude:
|a⃗| = √(aₓ² + aᵧ² + a_z²)

Dot product:
a⃗ · b⃗ = aₓbₓ + aᵧbᵧ + a_zb_z = ab cosθ

Cross product:
a⃗ × b⃗ = (aᵧb_z − a_zbᵧ)î + (a_zbₓ − aₓb_z)ĵ + (aₓbᵧ − aᵧbₓ)k̂
|a⃗ × b⃗| = ab sinθ

Projectile Motion Formula

The Projectile Motion Formula explains the motion of objects thrown into the air. It includes important concepts like range, time of flight, and maximum height, which are frequently asked in NEET Physics.

Projectile Motion:
x = ut cosθ,  y = ut sinθ − ½ gt²
y = x tanθ − (g / 2u² cos²θ) x²

T = (2u sinθ) / g,  R = (u² sin2θ) / g,  H = (u² sin²θ) / 2g

Work, Power, and Energy Formula

The Work, Power, and Energy Formula explains the basic principles of mechanics. These formulas are essential for understanding energy changes and are highly important for NEET Physics.

Kinetic energy:
K = ½ mv² = p² / 2m

Potential energy:
F = −dU/dx (for conservative forces)
U_gravitational = mgh,  U_spring = ½ kx²

Work done by conservative forces:
∮F_conservative · dr⃗ = 0

Work-energy theorem:

Mechanical energy:
E = U + K (conserved if forces are conservative)

Power:
P_avg = ΔW / Δt

Heat and Temperature Formula

The Heat and Temperature Formula covers important concepts of thermal physics like temperature scales, gas laws, and thermal expansion. These are key topics in NEET Physics.

Temp. scales:
F = 32 + (9/5)C,  K = C + 273.16

Ideal gas equation:
pV = nRT

van der Waals equation:
(p + a/V²)(V − b) = nRT

Thermal expansion:
L = L₀(1 + αΔT),

Thermal stress of a material:
F/A = Y(Δl / l)

Photoelectric Effect Formula

The Photoelectric Effect Formula explains how light interacts with matter. These formulas are important for solving questions from modern physics in NEET.

Photon’s energy:
