Across
- 2. A model or replica used for instructional or experimental purposes.
- 6. an object is translated, or moved linearly, in one direction and then back along the same path in the opposite direction until it returns to its starting point; the cycle is then repeated.
- 8. The rate with respect to time at which an object travels over distance. Speed is a scalar quantity
- 10. A working engagement of gears.
- 11. A measurement of the rate that an object changes position with respect to time regardless of the path taken. Speed is described by a magnitude making it a scalar quantity.
- 14. A moving mechanical device that performs a repetitive function.
- 17. occuring in equal intervals of time
- 18. A measurement of the rate that an object changes position and direction with respect to time. Velocity is described by a magnitude and direction making it a vector quantity.
- 19. an object moves back and forth in a reciprocating manner, but with elements of rotational motion like swinging.
- 21. The action of an object as it changes its position over time.
- 23. A scalar quantity measurement of how far an object has traveled from its starting point regardless of its staring or ending position.
- 24. To reproduce the conditions of (a situation, etc). To use a model to imitate certain conditions for purposes of study or training.
Down
- 1. A machine part that receives motion from another part
- 3. The study of motion of a system without consideration of forces acting within the system.
- 4. rotation around a fixed axis.
- 5. A visual display that demonstrates relationships between facts, concepts, or ideas. A graphic organizer guides the learner's thinking as they fill in and build upon a visual map or diagram.
- 7. 3D modeling where geometry is created with association to other geometry.
- 9. Turning around an axis or center point.
- 12. Any of a set of physical properties whose values determine the characteristics or behavior of something.
- 13. object moves in a straight line from one point in space to another.
- 15. A measurement between the starting position and final position of an object regardless of the path followed. Displacement is described by a magnitude and direction making it a vector quantity.
- 16. A smooth curve that maintains a constant radius from and angle with an axis.
- 20. 1. A relationship of one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range. 2. The action or actions that an item is designed to perform.
- 22. A rotating or sliding part in a mechanism used especially to transform rotational motion to linear motion or vice versa.
- 25. 1. Able to move quickly and easily. 2. A method of project management characterized by the division of tasks into short phases of work and frequent reassessment and adaption of plans.
