Physics Formulas and Concepts
Fundamental Formulas
m = ρ × V
Where m = mass, ρ = density, V = volume
m = W ÷ g
Where m = mass, W = weight, g = gravitational acceleration
m = F ÷ a
Where m = mass, F = force, a = acceleration
Key Concepts
Example Calculations
Example 1: Water Mass
Given: 1 liter of water
Density of water: 1000 kg/m³ (1 g/cm³)
Volume: 1 L = 0.001 m³
Calculation: m = 1000 × 0.001 = 1 kg
Result: 1 liter of water has a mass of 1 kilogram
Example 2: Steel Block
Given: Steel block 10cm × 10cm × 10cm
Density of steel: 7850 kg/m³
Volume: 0.1³ = 0.001 m³
Calculation: m = 7850 × 0.001 = 7.85 kg
Result: The steel block has a mass of 7.85 kilograms
Frequently Asked Questions
What's the difference between mass and weight?
Mass is the amount of matter in an object and remains constant regardless of location. Weight is the force exerted on that mass by gravity and varies depending on gravitational field strength.
How do I convert between different mass units?
Use the unit conversion method in the calculator. Common conversions include: 1 kg = 1000 g = 2.20462 lb = 35.274 oz. The calculator handles all conversions automatically.
Why does the same object weigh less on the Moon?
The Moon's gravitational acceleration is about 1/6th of Earth's (1.62 m/s² vs 9.81 m/s²). Since weight = mass × gravity, the same mass will have less weight on the Moon.
How accurate are density-based mass calculations?
Accuracy depends on the precision of density and volume measurements. Material density can vary due to temperature, pressure, and composition, so results are estimates for typical conditions.
