The CBSE twelfth Physics Examination 2024 is simply across the nook, so it is a good suggestion to brush up on these key formulation to nail the examination. Take a look at this helpful compilation of essential formulation from totally different chapters – do not miss it!
Take a look at the listing of essential formulae from the Class twelfth Physics Syllabus
Newton’s Legal guidelines of Movement:
F = ma (Pressure = mass x acceleration)
F = -dp/dt (Pressure is the same as the destructive fee of change of momentum)
ΣF = 0 (Internet pressure on an object at relaxation is zero)
Work and Power:
W = Fs (Work executed is the same as pressure x displacement)
KE = 1/2 mv^2 (Kinetic vitality is the same as 1/2 mass x velocity^2)
PE = mgh (Potential vitality is the same as mass x gravitational acceleration x peak)
Round Movement:
v = ωr (Tangential velocity is the same as angular velocity x radius)
a = rω^2 (Centripetal acceleration is the same as radius x angular velocity^2)
Gravitation:
G = Mm/r^2 (Common gravitational fixed system)
g = GM/R^2 (Acceleration resulting from gravity on Earth’s floor)
KE = -GmM/r (Escape velocity system)
Coulomb’s Regulation:
F = kq₁q₂/r² (Pressure between two level prices)
ok = 1/4πε₀ (Coulomb’s fixed)
Electrical Discipline:
E = F/q (Electrical discipline is pressure per unit cost)
E= – dV/dr (Electrical discipline is destructive gradient of potential)
Potential Distinction:
V = W/q (Potential distinction is figure executed per unit cost)
V = Ed (Potential distinction between two factors is electrical discipline x distance)
Capacitance:
C = Q/V (Capacitance is the ratio of cost saved to potential distinction)
C = ε₀A/d (Capacitance of parallel plate capacitor)
Ohm’s Regulation:
V = IR (Voltage is the same as present x resistance)
R = ρl/A (Resistance of a conductor)
Kirchhoff’s Legal guidelines:
ΣI in = ΣI out (Present coming into a junction is the same as present leaving)
ΣV = 0 (Sum of voltages round a closed loop is zero)
Energy:
P = VI (Energy is the same as voltage x present)
P = I²R (Energy dissipated in a resistor)
Magnetic Discipline resulting from a Present Aspect:
dB = μ₀/4π (I dl x r)/r³ (Magnetic discipline resulting from a present ingredient)
Pressure on a Shifting Cost:
F = qvB (Pressure on a shifting cost in a magnetic discipline)
Electromagnetic Induction:
e = -NdΦ/dt (Induced emf is the same as destructive fee of change of magnetic flux)
Mirror System:
1/f = 1/p + 1/q (Mirror system the place f is focal size, p is object distance, and q is picture distance)
Lens System:
1/f = (1/p) + (1/q) (Lens system)
Younger’s Double Slit Experiment:
λ = dΔx/L (System for calculating the wavelength of sunshine in Younger’s double slit experiment)
Photoelectric Impact:
KE = hν – φ (Kinetic vitality of photoelectron is the same as photon vitality minus work perform)
Bohr Mannequin:
E = -13.6 eV (Z²/n²) (Bohr’s mannequin system for vitality ranges of hydrogen atom)
Einstein’s Mass-Power Equivalence:
E = mc² (Power is the same as mass x velocity of sunshine squared).
