Section 1 Electrical Charge and
Force
Electric Force
• Electric force is the force of attraction or repulsion
between objects due to charge.
• The electric force at the atomic and molecular level is
responsible for most of the common forces we can
observe.
• The electric force is also responsible for effects that we
can’t see.
• Electric force depends on charge and distance.
• The electric force between two objects is proportional
to the product of the charges on the objects.
• The electric force is inversely proportional to the
square of the distance between two objects.

Section 1 Electrical Charge and
Force
Electric Force, continued
• Electric force acts through a field.
• An electric field is a region in space around a
charged object that causes a stationary charged
object to experience an electric force.
• One way to show an electric field is by drawing
electric field lines.
• Electric field lines point in the direction of the
electric force on a positive charge.
• The electric field lines around a positive charge point
outward.
• The electric field lines around a negative charge point
inward.

Electric Force, continued
• Electric field lines never cross one another.
• Field lines show both the direction of an electric
field and the relative strength due to a given
charge.
• More lines are drawn for greater charges to
indicate greater force.
