Quick Primer

Potential Energy (PE) is stored energy due to position or condition. For height, gravitational PE ≈ m·g·h. For stretched/compressed springs, elastic PE ≈ ½·k·x².

Kinetic Energy (KE) is energy of motion: ½·m·v². When an object falls, PE transforms into KE. In a closed system (ignoring losses), total mechanical energy stays nearly constant.

  • Increase height → increases PE.
  • Increase speed → increases KE a lot (depends on v²).
  • Energy can transform: PE ⇄ KE.

Tip: On Milestones, watch units and which variables change.
