7. The combination of all forces acting on an object.
9. the force of attraction or repulsion generated by moving or spinning electric charges
11. a push or a pull exerted on an object in order to change the motion of the object; force has size and direction.
12. any region in which a physical force has an effect.
14. The force that resists the start of sliding motion between two surfaces that are in contact and at rest.
15. any material that attracts iron and materials that contain iron

1. a region where a magnetic force can be detected.
2. how much ground an object has covered during its motion.
3. The force that opposes the movement of two surfaces that are in contact and are moving over each other.
5. The motion of a body when only the force of gravity is acting on the body.
