Across
- 6. Energy stored due to an object’s mass and height.
- 12. The SI unit of measurement for force.
- 13. A force that exists at the boundary between any two pieces of matter that are in contact with each other.
- 14. Information that supports or refutes a claim.
- 17. A graph of an object’s position (plotted on the vertical axis) at different points from an origin and the corresponding times (plotted on the horizontal axis) the object is at those distances.
- 19. A quantity that describes both speed and direction.
- 20. The distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop.
- 22. A push or pull.
- 23. The amount of matter in an object.
- 24. The combined force (magnitude and direction) acting on an object.
- 25. The rate at which an object moves, equal to the distance traveled per time interval.
- 27. In engineering design, something that limits the solution to a problem.
- 29. The distance a car travels during the reaction time.
Down
- 1. The scientific law that states that energy can be transferred or transformed, but it cannot be lost or destroyed.
- 2. The change of energy from one type to another, such as from chemical to thermal energy.
- 3. The change in speed and/or direction per unit time.
- 4. The observed phenomenon being measured.
- 5. The minimum requirements for the design to be successful.
- 7. The time interval between the moment a driver realizes a problem and when the driver applies the brakes.
- 8. The total distance a vehicle travels during the driver’s effort to bring the vehicle to a halt; distance traveled during the driver’s reaction time plus the braking distance.
- 9. The movement of energy from one object to another.
- 10. To change speed and/or direction per unit time.
- 11. When the magnitude and direction of more than one force acting on an object give a net force unequal to zero.
- 15. Any representation of a system (or its components) used to help one understand and communicate how it works.
- 16. The energy an object has because of its motion.
- 18. When the magnitude and direction of more than one force acting on an object results in zero net force.
- 21. Information gathered from an experiment or observations.
- 26. The decrease in speed per unit time.
- 28. A group of interacting objects or processes. Every system includes components, interactions, and boundaries.
