Physics Terms

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.

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
