A scary movie

( Friction, static electricity, repel, attract )
 
Some movies can be very scary.

These movies may make people close their eyes or even scream.

Some movies are so scary that people say their hair stands on end.

Of course, this is just an expression, but there actually is a way to make a person¡¯'s hair stand on end.

You don¡¯'t have to go to a scary movie.

All you have to do is use a device called a Van de Graaff generator.
¿©·¯ºÐÀº Van de Graaff ¹ßÀü±â¶ó°í ºÒ¸®´Â ÀåÄ¡¸¸ ÁغñÇÏ½Ã¸é µË´Ï´Ù.
 
To understand how this device works, you have to know something about (1)________________.

There are several ways to build up electrical charge in an object.
¹°Ã¼¿¡ Á¤Àü±â¸¦ À¯¹ßÇÏ´Â ¹æ¹ý¿¡´Â ¿©·¯ °¡Áö°¡ ÀÖ½À´Ï´Ù.
 
One way is to use (2)_____________.
ÇÑ °¡Áö ¹æ¹ýÀº ¸¶ÂûÀ» ÀÌ¿ëÇÏ´Â °ÍÀÌÁö¿ä.
 
For example, imagine that you rub an inflated balloon through your hair.
¿¹¸¦ µé¸é °ø±â°¡ µç dz¼±À» ¸Ó¸®Ä«¶ô¿¡ ¹®Áö¸¥´Ù°í ÇØº¸¼¼¿ä.
 
Rubbing produces friction.
¹®Áö¸£¸é ¸¶ÂûÀÌ »ý°Ü³³´Ï´Ù.
 
Friction causes electrons to move from your hair to the balloon.
¸¶ÂûÀº ÀüÀÚ¸¦ ¿©·¯ºÐÀÇ ¸Ó¸®Ä«¶ô¿¡¼­ dz¼±À¸·Î À̵¿½Ãŵ´Ï´Ù.
 
Electrons have a negative charge.
ÀüÀÚ´Â À½Àü±â¸¦ °¡Áý´Ï´Ù.
 
The balloon gains electrons and becomes negatively charged.
dz¼±Àº ÀüÀÚ¸¦ ¾ò¾î À½Àü±â¸¦ ÃàÀüÇÕ´Ï´Ù.
 
Your hair loses electrons.
¸Ó¸®Ä«¶ôÀº ÀüÀÚ¸¦ ÀÒ°Ô µÇÁö¿ä.
 
As your hair loses negative charges, it becomes positively charged.
´ç½ÅÀÇ ¸Ó¸®Ä«¶ôÀÌ À½Àü±â¸¦ ÀÒ°Ô µÇ¸é ¾çÀü±â¸¦ ÃàÀüÇÏ°Ô µË´Ï´Ù.
 
Notice that the hair and the balloon have opposite charges.
¸Ó¸®Ä«¶ô°ú dz¼±ÀÌ ¹Ý´ëÀÇ Àü±â¸¦ ÃàÀüÇÏ°Ô µÈ´Ù´Â »ç½ÇÀ» ¾Æ½Ã°ÚÁÒ.
 
Opposite charges (3)____________.
¹Ý´ëÀÇ ÀüÇÏ´Â ¼­·Î ²ø¾î´ç±é´Ï´Ù.
 
If you bring the balloon close to your hair, the two will attract each other.
´ç½ÅÀÌ Ç³¼±À» ¸Ó¸® °¡±îÀÌ·Î °¡Á®°¡¸é ±× µÑÀº ¼­·Î ²ø¾î´ç±é´Ï´Ù.
 
So static electricity can cause objects to attract each other.
Á¤Àü±â°¡ µÎ ¹°Ã¼¸¦ ¼­·Î ²ø¾î´ç±âµµ·Ï ¸¸µå´Â °ÍÀÔ´Ï´Ù.
 
Static electricity can also cause objects to repel each other.

This is how a Van de Graaff generator works.

This device has a metal dome.
ÀÌ Àåºñ´Â ö·Î ¸¸µé¾îÁ® µ¼ÇüÀ¸·Î »ý°å½À´Ï´Ù.
 
Electrons collect on the metal dome.
ÀüÀÚ°¡ ÀÌ µ¼ÇüÀ¸·Î µÈ ö ¾È¿¡ ¸ðÀÔ´Ï´Ù.
 
If someone touches the dome, the electrons will flow through the person.
´©±º°¡ ÀÌ µÕ±Ù µ¤°³¸¦ ¸¸Áö°Ô µÇ¸é, Àü±â°¡ »ç¶÷¿¡°Ô È帨´Ï´Ù.
 
These electrons will collect on the person¡¯'s hair.

The hair will become covered with negative charges.

Like charges repel.
°°Àº ÀüÇÏ´Â ¹Ð¾î³»Áö¿ä.
 
As a result, the strands of hair will repel each other.
±× °á°ú ±× ¸Ó¸®ÀÇ ½¢Àº ¼­·Î¸¦ ¹Ð¾î³»°Ô µË´Ï´Ù.
 
This causes the hair to stand on end.

See, you don¡¯'t even have to watch a scary movie!
