SUMMARY
The metric units for various physical measurements are defined as follows: velocity is measured in meters per second (m/s), mass in kilograms (kg), kinetic energy in joules (J), height in meters, and acceleration due to gravity in meters per second squared (m/s²). The discussion emphasizes the importance of dimensional analysis for converting between units of energy, highlighting that all energy can be expressed in joules. The formula for acceleration is clarified as the change in speed divided by the change in time, reinforcing the unit of acceleration as m/s².
