Work and Machines
Across
- 2. a unit of measurement, used to measure force
- 5. is the universal force that attracts objects to each other
- 6. the pivot of a lever
- 10. two or more simple machines combined
- 12. Sharpened edge to cut or separate
- 13. Wheels with teeth
- 14. a type of simple machine with three different classes
- 16. output force, what you are lifting
- 19. Wheels with a rope, less force due to more distance.
- 21. the sum of all the forces acting on an object
- 23. used to measure the efficiency/effectiveness of a machine
- 25. Force x Distance
- 26. how much work something can get done in comparison to other machines/tools/people
- 29. balance when the net forces are zero
Down
- 1. the load/output force
- 3. A unit of measurement for energy (kinetic/potential)
- 4. wedge and an inclined plane combined
- 7. a tool or combination of difference tools that make the effort in work decrease
- 8. an object when thrown
- 9. When an object starts to move it is due to _________ _______, or how the forces are no longer balanced.
- 11. Wheel+_____ helps an object roll.
- 12. ______+ axle is used on multiple types of vehicles.
- 15. Ramp, used to decrease force by increasing distance
- 17. a machine that can make work easier by increasing the distance and decreasing the amount of force used.
- 18. when forces on an object are the same or equal so the object remains still and unmoving.
- 20. mass x velocity
- 22. the outcome of effort in work
- 24. force that opposes the motion of two subjects
- 27. an objects natural tendency to keep moving
- 28. the force put into a work (opposite of output)
