Forces

3. The opposite direction to where a compass needle is pointing.
10. A magnet which is created by an electric current running through a wire around a piece of metal.
11. To push away.
13. A solid translucent plastic which can act as an insulator.
14. A device can be used to determine if something has been electrostatically charged.
17. The lowest velocity that a body must have in order to escape the gravitational attraction of planet or another object.
18. The direction in which a compass needle points.
19. An interaction of a push, pull or twist on an object.
20. A charge where there is more protons than electrons.
21. A region where objects within that region are impacted upon by a force.
23. To have the properties of a magnet.

1. A charge where there is more electrons than protons.
