Across
- 2. An object in motion stays in motion at a constant velocity and an object at rest stays at rest unless acted on by a net external force
- 3. A picture drawn with all forces acting on an object labeled
- 4. Usually this value is taken as a half of the smallest increment of the instrument scale.
- 6. A push or pull
- 7. gravity is not balanced by an equal and opposite normal force. formula: mg+ma
- 10. Distance over time, only a magnitude, not including a direction
- 11. The curved path an object takes when being thrown or launched
- 13. Change in speed over time
- 18. can be found using the formula Vt^2/r where Vt= tangent velocity of the object
- 21. the “center seeking” force that makes an object move in a circle
- 22. A quantity with magnitude + direction
- 23. is represented with the vector -9.8
- 25. A pulling force that arises from a rope, string, or other long thin material resists being pulled apart without stretching significantly
- 26. The magnitude of the force exerted by a spring is proportional to the amount it is stretched
- 27. Every action has an equal and opposite reaction.
Down
- 1. is not real! Says there is a force acting outward on an object as it rotates in a circle instead of inward.
- 5. The absolute uncertainty divided by the measured value
- 8. Finding the linear fit for non-linear data that shows the relationship between x and y
- 9. How far an object is from its starting position over time
- 12. How much ground a unit has covered over time
- 14. The X and Y broken-down parts of a vector
- 15. Occurs when surfaces are slipping past each other
- 16. Speed + Direction, is a vector
- 17. Occurs between two surfaces that are not slipping relative to each other
- 19. rotation along a circular path
- 20. An object with mass accelerates when acted on by a net force
- 24. Time needed to complete one revolution
