Metric Notes Part 1

The metric system is a universal measurement standard noted for its simplicity and ease of use. It allows for straightforward conversions between units, making it a preferred system globally. The metric system is based on the number 10, enhancing its usability. Key concepts include mass, which refers to the amount of matter in an object, and weight, which is the gravitational force on that object and can vary with location. The fundamental units include meters for length, kilograms for mass, and seconds for time, forming the basis of the MKS system frequently utilized in physics and engineering.

  1. Metric Notes Part 1

  2. Why do we use the metric system? It is a standard international measurement and is used because it is easier to convert between units. It’s international! It is based on 10.

  3. Mass & Weight Mass measures the amount of matter in an object. Weight measures the force of gravity on an object. Weight changes depending on location but mass does not.

  4. Physics units Length = m (meter) Mass = kg (kilogram) Time = s (second) Weight = N (Newton)

  5. Fundamental units are meter, kilogram, and second. Derived units (such as meter per second or m/s) are based on fundamental units.

  6. MKS MKS is a system of units based on measuring length in meter, mass in kilograms, and time in seconds. MKS is generally used in beginning physics and engineering. (it stands for meters, kilograms, seconds!)
