Unit 1 Flashcards
Electric charge (can be + or -)
Is a fundamental property of matter. It is associated with the particles that make up the atom - protons and electrons
Net electric charge
can be +,-,0
is an excess of either protons or electrons
Properties of charge 1.
like charges repel each other and opposite charges attract
Properties of charge 2.
charge is quantized. Any observable amount charge is integral multiple of the fundamental amount of charge e. q=+-ne
Properties of charge 3.
The net charge of an isolated system is conserved (doesnt change)
The force of interaction between point charges is described by
Coulomb’s law
is the source of an electric field in the surrounding space
charge
If a charge is placed within the field, it will experience an _______ ____ exerted by the ______
electric force, field
Kinematics equation 1
V= Vo + at
Kinematics equation 2
Delta X= ( V + Vo/2) t
Kinematics equation 3
Delta X= Vo + 1/2at^2
Kinematics equation 4
V^2= Vo^2 + 2adeltax
