Across
- 5. The rate at which work is performed or energy is transferred, measured in Watts (P = W/t)
- 6. Energy transformed by nonconservative forces (like friction) into non-mechanical forms, typically thermal energy.
- 8. The transfer of energy through the application of a force over a parallel displacement
- 9. The principle that total mechanical energy remains constant if only conservative forces do work on a system.
- 11. The energy an object possesses due to its linear motion, calculated as K = 1/2mv^2
- 12. The principle stating that the net work done on an object equals its change in kinetic energy (Wnet = K)
- 13. The energy stored in an object when it is compressed or stretched, such as a spring (Us = 1/2kx^2)
- 15. The relationship stating the force exerted by a spring is proportional to its displacement (Fs = -kx)
Down
- 1. The total energy of a system, equal to the sum of its kinetic and potential energies.
- 2. Energy stored in a system due to an object's position within a gravitational field, often Ug = mgh
- 3. The SI unit for work and energy, equivalent to one Newton-meter (1 J = 1 Nm)
- 4. A force, like gravity, where the work done is independent of the path taken between two points.
- 7. A force, like friction, where the work done depends on the path taken and often dissipates energy as heat.
- 10. A defined collection of objects whose interactions are analyzed; energy can be transferred in or out of its boundaries.
- 14. A physical quantity that has magnitude only, with no direction, such as work and energy.
