Study Notes
Mass Definition
- Mass is the amount of matter or substance that makes up an object
- Measured in units of kilograms (kg)
- Remains the same regardless of location or gravity
Weight vs Mass
- Weight depends on gravity and changes with location (e.g., lighter on the moon)
- Mass does not change with gravity, remaining constant
Importance of Mass
- Vital role in scientific community
- Used to measure small substances in laboratory settings
- More precise than weight, allowing for accurate measurements of tiny objects
- Universal unit of measurement, facilitating communication across the world and in space
Unique Properties of Mass
- Does not change with differences in gravity, making it essential for space experiments and communication
- Enables accurate replication of experiments in different gravitational environments
