  1. 5. The rate at which work is performed or energy is transferred, measured in Watts (P = W/t)
  2. 6. Energy transformed by nonconservative forces (like friction) into non-mechanical forms, typically thermal energy.
  3. 8. The transfer of energy through the application of a force over a parallel displacement
  4. 9. The principle that total mechanical energy remains constant if only conservative forces do work on a system.
  5. 11. The energy an object possesses due to its linear motion, calculated as K = 1/2mv^2
  6. 12. The principle stating that the net work done on an object equals its change in kinetic energy (Wnet = K)
  7. 13. The energy stored in an object when it is compressed or stretched, such as a spring (Us = 1/2kx^2)
  8. 15. The relationship stating the force exerted by a spring is proportional to its displacement (Fs = -kx)

  1. 1. The total energy of a system, equal to the sum of its kinetic and potential energies.
  2. 2. Energy stored in a system due to an object's position within a gravitational field, often Ug = mgh
  3. 3. The SI unit for work and energy, equivalent to one Newton-meter (1 J = 1 Nm)
  4. 4. A force, like gravity, where the work done is independent of the path taken between two points.
  5. 7. A force, like friction, where the work done depends on the path taken and often dissipates energy as heat.
  6. 10. A defined collection of objects whose interactions are analyzed; energy can be transferred in or out of its boundaries.
  7. 14. A physical quantity that has magnitude only, with no direction, such as work and energy.
