2.1.1 strength or energy as an attribute of physical action or movement.
2.2 Blananced vs. Unblanced Forces
2.2.1 Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime
there is a balanced force on an object, the object stays still or continues moving continues to move at
the same speed and in the same direction. When balanced forces act on an object at rest, the object
will not move. If you push against a wall, the wall pushes back with an equal but opposite force.
Neither you nor the wall will move. Forces that cause a change in the motion of an object are
2.3 Net Force
2.3.1 A net force is defined as the sum of all the forces acting on an object.
2.4.1 the action or process of moving or being moved.
2.5 Newtons 3 Laws
2.5.1 I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is
applied to it. II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.
Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the
direction of the force vector is the same as the direction of the acceleration vector. III. For every action there is an
equal and opposite reaction.
2.6.1 a tendency to do nothing or to remain unchanged.
2.7 Free Body Diagram
2.7.1 a graphical illustration used to visualize the applied forces, movements, and resulting reactions
on a body in a given condition.
2.8.1 the chemical element of atomic number 12, a silver-white metal of the alkaline earth
series. It is used to make strong lightweight alloys, especially for the aerospace
industry, and is also used in flashbulbs and pyrotechnics because it burns with a
brilliant white flame.
2.9.1 the interaction of electric currents or fields and magnetic fields.

4.1 Transverse vs Longitudinal
4.1.1 Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which
particles of the medium move in a direction parallel to the direction that the wave moves. ... This type of wave is a longitudinal wave.
4.2 EM Waves
4.3 Sound Waves
4.3.1 a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
4.4.1 the action of interfering or the process of being interfered with.
4.5.1 the process or action by which one thing absorbs or is absorbed by another.
4.6.1 the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a
medium of varying density.
4.7.1 the throwing back by a body or surface of light, heat, or sound without absorbing it.
4.8.1 the process by which a beam of light or other system of waves is spread out as a result of passing through
a narrow aperture or across an edge, typically accompanied by interference between the wave forms
4.10 Wave Descriptions
4.10.1 the transport of energy without the transport of matter. In conclusion, a wave can be described as a disturbance that travels
through a medium, transporting energy from one location
