Physics chapter 2

1. Four what is the spring constant if the spring is extended by 10m, and the force that pulls on the spring is 50N?
3. Resistance that arises when two surfaces move against one another.
6. a force that acts between the two poles of a magnet. It can be an attraction or repulsion.
10. A force that arises in a rope if pullen on both ends.
11. An instrument with a helical spring that is used to measure forces.
13. The sum of the forces acting on an object.
14. The force that an object exerts in whatever it is resting on as a result by the force of gravity acting on the object
15. The force on earth that attracts you and the objects around you.
16. State of an object when the only force acting on it is gravity.

1. what is the spring constant if the spring is extended by 10m, and the force that pulls on the spring is 40N?
2. concept in physics that makes clear how objects change one another’s shape and/or motion.
4. State in which an object has no weight.
5. way of representing size, direction and point of application as an arrow.
7. the increase in the length of the spring when a force is exerted on it.
8. A force that resists a motion and acts against that motion
9. what is the force exerted by gravity on an 10kg object? Round to one integer.
12. ratio that you use to draw forces, the size of the force is indicated by an arrow.
