Across
- 1. The point on which a lever rests or is supported and on which it pivots.
- 3. 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.
- 5. 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.
- 6. A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
- 8. 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
- 9. A variable whose variation does not depend on that of another.
- 12. A set of principles on which the practice of an activity is based.
- 13. A statement of fact, deduced from observation, to the effect that a particular natural or scientific phenomenon always occurs if certain conditions are present.
- 15. depends on independent variable.
Down
- 2. The ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine
- 4. Any of the basic mechanical devices for applying a force, such as an inclined plane, wedge, or lever.
- 7. Mental or moral strength or power.
- 10. Operate or function, especially properly or effectively.
- 11. The principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
- 14. The secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates.
