Grades Nine Through Twelve  Physics
Science Content Standards.
Standards that all students are expected to achieve in the course of their studies are
unmarked.
Standards that all students should have the opportunity to learn are marked with an
asterisk (*).
Motion and Forces
1.
Newton's laws predict the motion of most objects. As a basis for
understanding this concept:
a.
Students know how to solve problems that involve constant speed and
average speed.
b.
Students know that when forces are balanced, no acceleration occurs;
thus an object continues to move at a constant speed or stays at rest
(Newton's first law).
c.
Students know how to apply the law F=ma to solve onedimensional
motion problems that involve constant forces (Newton's second law).
d.
Students know that when one object exerts a force on a second object,
the second object always exerts a force of equal magnitude and in the
opposite direction (Newton's third law).
e.
Students know the relationship between the universal law of gravitation
and the effect of gravity on an object at the surface of Earth.
f.
Students know applying a force to an object perpendicular to the
direction of its motion causes the object to change direction but not
speed (e.g., Earth's gravitational force causes a satellite in a circular
orbit to change direction but not speed).
g.
Students know circular motion requires the application of a constant
force directed toward the center of the circle.
h.
* Students know Newton's laws are not exact but provide very good
approximations unless an object is moving close to the speed of light or
is small enough that quantum effects are important.
i.
* Students know how to solve twodimensional trajectory problems.
j.
* Students know how to resolve twodimensional vectors into their
components and calculate the magnitude and direction of a vector from
its components.
