forces. These effects help students to understand electric motors and generators.

OBJECTIVES

PS4a: Objects change their motion only when a net force is applied. Laws of motion are
used to calculate precisely the effects of forces on the motion of objects. The magnitude
of the change in motion can be calculated using the relationship F = ma, which is
independent of the nature of the force. Whenever one object exerts force on another, a
force equal in magnitude and opposite in direction is exerted on the first object.
PS4c: The electric force is a universal force that exists between any two charged objects.
Opposite charges attract while like charges repel. The strength of the force is proportional
to the charges, and, as with gravitation, inversely proportional to the square of the
distance between them.
PS5b: All energy can be considered to be either kinetic energy, which is the energy of
motion; potential energy, which depends on relative position; or energy contained by a
field, such as electromagnetic waves.
