Work, KE,PE and Conservation of Energy
Across
- 7. conservation total energy of an isolated system is constant
- 8. power work done in a time interval divided by the time interval
- 9. when a force acts on something that undergoes a displacement from one position to another
- 12. force force that does work that depends on path
- 14. differential is the total differential of a function and requires the use of partial derivatives if the function involves more than one dimension
- 15. point position where the assumed conservative, net force on a particle, given by the slope of its potential energy curve, is zero
- 18. negative of the work done acting between two points in space
- 19. function of position, energy possessed by an object relative to the system considered
Down
- 1. graph of a particle’s potential energy as a function of position
- 2. energy source that is not renewable, but is depleted by human consumption
- 3. quantity one that cannot be created or destroyed, but may be transformed between different forms of itself
- 4. force force that does work independent of path
- 5. position where the velocity a particle, in one-dimensional motion, changes sign
- 6. energy source that is replenished by natural processes, over human time scales
- 10. energy energy of motion, one-half an object’s mass times the square of its speed
- 11. rate of doing work
- 13. energy sum of the kinetic and potential energies
- 16. theorem net work done on a particle is equal to the change in its kinetic energy
- 17. work work done by all the forces acting on an object
