7 Science

1. move forward using force
3. the direction of force when two same poles of a magnet come close to each other
6. an increase in this will decrease the gravitational pull
7. what forces always come in
9. the rate at which something moves
10. poles of a magnet that attract each other
13. Newton's law stating every action has an equal and opposite reaction
17. forces that are greater in one direction resulting in a change in motion
18. the measurement of how much gravity pulls on an object
19. more of this on an electromagnet increases the strength of the magnetic field
20. type of electricity that occurs when there is an imbalance of electric charges between materials
21. Newton's law stating an object at rest will stay at rest until acted on by an external force
22. the sum of all the forces acting on an object

2. a device to measure weight or mass
4. a type of magnet that can be turned on and off with electricity
5. forces that are opposite in direction and equal in size resulting in no change of motion
8. Newton's law stating mass = force x acceleration
11. part of a magnet where the magnetic effect is strongest
12. force that attracts objects towards the center of the Earth
14. a property of matter stating objects have a tendency to stay in their position until acted upon
15. move toward oneself using force
16. the amount of matter in an object
19. an object or type of material that allows the flow of a charge
