Important Formulas For Class Science - Chapterwise
Here’s a clear and concise guide to important science formulas, sorted by topic -
Force and Motion
Speed = Distance / Time
Velocity = Displacement / Time
Acceleration = Change in Velocity / Time
Force = Mass × Acceleration (F = m × a)
Work done = Force × Distance (W = F × d)
Gravitation and Pressure
Pressure = Force / Area (P = F / A)
Density = Mass / Volume (ρ = m / V)
Light and Sound
Wave speed = Frequency × Wavelength (v = f × λ)
Ohm’s law: Voltage = Current × Resistance (V = IR)
Electricity and Magnetism
Power = Voltage × Current (P = VI)
Chemistry (Reactions and Moles)
Number of Moles = Given Mass / Molar Mass
pH = -log[H+]
Biology
Photosynthesis: 6CO2+ 6H2O → C6H12O6 + 6O2
Units and Measurements
Length → meter (m)
Mass → kilogram (kg)
Time → second (s)
Electric Current → ampere (A)
Temperature → Kelvin (K)
Amount of Substance → mole (mol)
