| what happens when you put a north side of a magnet to another north side | they seperate |
| seismagraph record seismic waves coming from an earthquake which type of seismic wave would arrive first to a seismicgraph | p-waves |
| seismic waves (s and p )are vibrations that are different depending or the proclaymation | direction |
| What word means an attraction or repulsion interaction between any 2 charged objects? | electrical force |
| Where is (are) the strongest section(s) on a magnet? | the ends |
| The force of a magnetic field changes with _. | distance |
| What would happen to an object with a northern polarity if placed outside of the field of an object with a southern polarity? | nothing its outside |
| How could you get an object near this magnet to move to the right? | place the southern part of another magnet on the right by the south part |
| One bar magnet sits on a table, and a rubber band suspends another magnet above it. In the view on the left, the upper magnet is held in place and cannot move. In the view on the right, the upper magnet has been released. | magnetic and gravitational potential energy decreases and elastic increases |
| What is a field of force surrounding a permanent magnet or moving charged particles? | magnetic field |
| As two positive charges get closer together, which of the following statements is true? | the electrical PE increases since the distance between the charges decreases. |
| Two positively charged particles are attached to springs. A metal sphere is placed near each charged particle as shown in the diagram. | The elastic potential energy of both springs will increase.This answer is correct. |
| Which type of objects permit the flow of electricity? | conductors |
| Attractive or repulsive interactions between any 2 charged objects. | electrical Force |
| If you charged a balloon by rubbing it on your hair and stuck it to a wall, what would happen if you turned the other side of the balloon to the wall? | it will repel |
| What are materials that impede the free flow of electrons? | insulaters |
| what does W<E<T<D<C<C mean | W=weathering E=erosion T= transformation D= decomposition C=compaction C= centimentation |
