Study Notes
Volume
- Volume measures the space an object occupies, given in three dimensions: length, width, and height.
- Common units of measurement are milliliters (mL) and cubic centimeters (cm³).
Weight
- Weight quantifies the gravitational force on an object, typically measured in pounds or ounces.
- A person's weight varies by location; for instance, 60 lbs on Earth becomes 10 lbs on the Moon due to diminished gravity.
- Weight differs from mass, which remains constant regardless of location in the universe.
Mass
- Mass represents the quantity of matter in an object, measured in grams.
- Mass is invariant, meaning it does not change based on location.
Density
- Density is defined as mass per unit volume, calculated by dividing mass by volume.
- Units for density include grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).
- Water has a density of 1 g/mL; substances with a density less than this will float.
Graduated Cylinder
- A graduated cylinder is a cylindrical instrument used for accurately measuring liquid volume.
Displacement Method
- A technique to measure the volume of irregular objects by observing water level changes.
- Initial water level is recorded, and after placing the object in water, the new level is noted; the volume is the difference between the two levels, measured in mL.
Metric System
- The metric system is an internationally used measurement system, favored in scientific and global contexts.
- It employs a base of ten and includes units such as centimeter, meter, gram, milliliter, and liter.
Gram
- A gram is the primary metric unit for measuring mass.
Milliliter (mL)
- Milliliter is the standard metric unit for volume measurement, with 1000 mL equating to one liter.
Cubic Centimeter (cm³)
- Cubic centimeter is the unit for solid volume, equivalent to 1 mL.
Density of Water
- Water’s density is precisely 1 gram/milliliter (1 g/mL).
Buoyancy
- Objects with a density lower than 1 g/mL will float in water.
