Across
- 1. force- Effort distance is the distance through which a machine moves or distance through which the effort force is applied to a machine. Resistance distance is the distance through which the resistance force is applied or the distance through which the object moves.
- 4. The principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
- 5. Mental or moral strength or power.
- 6. The point on which a lever rests or is supported and on which it pivots.
- 10. A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
- 12. advantage- The ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine
- 14. machine- Any of the basic mechanical devices for applying a force, such as an inclined plane, wedge, or lever.
Down
- 2. A set of principles on which the practice of an activity is based.
- 3. A statement of fact, deduced from observation, to the effect that a particular natural or scientific phenomenon always occurs if certain conditions are present.
- 7. force- In physics, resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pounds
- 8. Operate or function, especially properly or effectively.
- 9. variable.
- 11. The secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates.
- 13. machine- A compound machine is a combination of two or more simple machines. There are six types of simple machines: a lever, a pulley, an inclined plane, a wheel and axle, a wedge and a screw. One example of a compound machine is a bicycle. The wheels and pedals each form a separate wheel and axle system.independent variable- A variable whose variation does not depend on that of another.
