Sure! Here are some common science formulas that are often taught in 10th-grade science:
1. Physics Formulas:
– Speed (v) = Distance (d) / Time (t)
– Acceleration (a) = (Final velocity (v) – Initial velocity (u)) / Time (t)
– Force (F) = Mass (m) × Acceleration (a)
– Weight (W) = Mass (m) × Acceleration due to gravity (g)
– Density (ρ) = Mass (m) / Volume (V)
– Work (W) = Force (F) × Displacement (d) × cos(θ) [where θ is the angle between force and displacement]
– Power (P) = Work (W) / Time (t)
– Pressure (P) = Force (F) / Area (A)
– Ohm’s Law: Voltage (V) = Current (I) × Resistance (R)
2. Chemistry Formulas:
– Mole (n) = Mass (m) / Molar mass (M)
– Ideal Gas Law: PV = nRT [where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature in Kelvin]
– pH = -log[H+] [where H+ is the concentration of hydrogen ions in moles per liter]
– Energy change (ΔH) = Heat absorbed or released in a chemical reaction
– Rate of reaction = Δ[C] / Δt [where Δ[C] is the change in concentration of a reactant or product, and Δt is the change in time]
3. Biology Formulas:
– Photosynthesis: 6 CO2 + 6 H2O → C6H12O6 + 6 O2
– Respiration: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy (ATP)
– Genetics: Punnett square for predicting offspring genotypes based on parental genotypes.
– Hardy-Weinberg equilibrium equation: p^2 + 2pq + q^2 = 1 [where p and q are allele frequencies]
These are just some fundamental formulas commonly taught in 10th-grade science. Depending on the specific curriculum and syllabus, there may be more formulas and concepts to cover. Always consult your textbook or teacher for the formulas and concepts relevant to your course.
