Types of Forces

2. one of the details that need to be known to measure force (how big an object is)
5. the force that opposes contact with another object (if you push on it, it pushes back.) \
6. Force with which objects tend to return to its original state after being stretched or compressed by an external force. (challenge)
11. the combination of all forces acting on an object
12. when objects must touch for the force to work
13. There are two factors that impact the force of gravity. One is mass, what is the other one?
14. the force between two poles
15. what two factors can impact friction? One is the size of the force, what is the other?
16. forces of gravity act between all objects in the universe that have mass
17. how forces are measured

1. the pulling force between two objects with mass
3. a push or pull
4. the force between positive and negative charges
7. a force that opposes motion
8. a regular push or pull such as moving a chair
9. when the objects do not have to touch for the forces to work
10. one of the details that need to be known to measure force (how fast it is moving)
