What is the build up of electrical charges in one place called?

Causes by friction EX: -- static cling clothing from the dryer. --lightening. --hair to raise when rubbed by ballon.

--shocked when you touch a handle after walking across surface

• electrical current flowing electricity

• Electrostatic

  static electricity

• Electrical grounding

• frictional conductor/insulator

  Electronics

Particles _______ to one another causing electrostatic to occur

• attract

• repel

• nothing changes

Items that have opposite charges ______ causing the 2 to pull toward on another

EX: Na+ Cl-

--Aluminum coke can rolling toward a charged rod

• attract

• repel

• cancel out

• sing song

NGSS.MS-PS2-5

Items that have like charges ______ causing the 2 to push away from one another

EX: Na+ Li+

--a packing peanut can push away from a charged rod

• attract

• repel

• cancel out

• sing song

If the distance between two electric charges is reduced what happens to the electrostatic attraction/re[ulsion force?

• increases

• decresase

• is unchanged

• distane and force are unrelated

NGSS.HS-PS3-5

If the charges _____________ what happens to the electrostatic attraction/re[ulsion E force?

Remember the size of the charge works like the size of a sun or planet, mass affects attracting G force.

• increases charge increase force

  decrease charge decrease force

• increases charge decrease force

  decrease charge increase force

• increases or decrease charge no change to force

• The Bigger they are the harder they fall.

Building up of charge due the the transferring of electrons when 2 objects rub together

• friction

• grounding

• conduct

• induct

The removing of excess charges

required by law of safety when wiring a house

• friction

• grounding

• conduct

• induct

Electricity that flows in a closed path is called a

• potential difference

• current
• circuit
• resistor
