Standards/Enduring Understandings

All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion. The sun's gravitational pull holds the earth and other planets in their orbits, just as the planets' gravitational pull keeps their moons in orbit around them.

Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.

The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.

Every object exerts gravitational force on every other object. The force depends on how much mass the objects have and on how far apart they are. The force is hard to detect unless at least one of the objects has a lot of mass.

Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.

In most familiar situations, frictional forces complicate the description of motion, although the basic principles still apply.

S11.C.3.1 Use the principles of motion and force to solve real-world challenges.

S11.C.3.1.3 Describe the motion of an object using variables (i.e., acceleration, velocity, displacement).
