Study Notes
Mass and Weight
- Mass is an inherent property of matter.
- Mass is the measure of the quantity of matter a body contains.
- Mass does not vary with position.
- Weight is the result of mass and gravitational attraction.
- Weight varies with distance from the center of the earth.
- The basic unit of mass in the SI system is the kilogram.
- The 'gram' is often used for small quantities of chemicals in laboratories.
Length
- Length is used to express properties such as atomic radius, bond length, and wavelength of electromagnetic radiation.
- Fractional units of length are often used for these quantities, such as nanometers (nm) and picometers (pm).
Volume
- Volume is the amount of space occupied by a three-dimensional object.
- It does not depend on shape.
- The liter (L) is a common unit for the volume of liquids and gases.
- The SI unit of volume is the cubic meter (m³).
