Forces Vocabulary

5. describes how fast something moves but does not tell you direction
7. two (or more) forces acting on an object are not equal in size. This means that the resultant force is not zero.
9. A quantity with both size and direction. push: a vector quantity (magnitude and direction) that moves an object away from the source of the force.
11. is a force that causes a 1kg mass to accelerate at a rate of 1m/s2
12. The tendency to resist changes in motion
13. is the speed of an object in a particular direction.
14. a vector quantity (magnitude and direction) that moves an object away from the source of the force
15. forces that only act between objects that are touching
16. is a push or a pull exert on an object
17. The force pulling objects toward Earth

1. when two forces acting on an object are of the same size and act in opposite directions. The resultant force is zero.
2. scale: is a mechanical device used to measure weight or force rather than mass.
3. a vector quantity (magnitude and direction) that moves an object towards the source of the force.
4. the rate at which velocity changes over time.
6. orientation at which an object moves, points, or acts. Defines "which way" something is heading.
8. The size, quantity, or strength of a physical quantity, represented by a numerical value. It measures “how much” or “how strong” something is.
10. forces that can act at a distance
