Electric Charge and Force
- Electric charger
- Rubbing Objects together
can charge them
- Electric Charge comes
in two distinct types
- Atoms have positive, negative,
and neutral particles
- Electric charge is
quantized
- A Coulomb is a large
amount of charge
- Electric charge can be
transferred between objects
- Charging by contact
varies with the material
- An Electric charge can attract a
neutral objects
- not all materials are
good conductors
- Electric Force
- Coulomb´s law describes
the electric force
- Electric force acts along a
line between the charges
- Electric force is similar
togravitational force
- Electric forces keep most
objects close to neutral
- Combining Electric force
- Electric Forces add by
vector addition
- Electric Forces can be
added graphically
- A spherical distribution of charge acts
just like a point charge.
