=Circular Motion: The movement of an object at constant speed around a circle with fixed radius. = =Newton and Gravity: Newton concluded that any two objects in the Universe exert gravitational attraction on each other. = > ====
 * =Axis: Straight line around which rotation takes place.=
 * =Revolution: Object turns around the external axis.=
 * =Rotational Speed: number of rotations per unit of time. Ex Carousel horses travel at same rotation speed but different trangential speed.=
 * =Trangential Speed: Is radical distance times the rotational speed. V=rw=
 * =Centripetal Force: Force that causes an object to follow a circular path.=
 * =Centrpental Acceleration: Always points toward the center of the circular motion.=
 * =Centrpental Acceleration: Always points toward the center of the circular motion.=
 * ==Gravity: is a constant force exerted by objects that have mass.==
 * ==Weight: is the pull of gravity==
 * ==Universal Gravitational and Mass: As the mass of either object or both object increases, the force of gravitational attraction increase.==
 * ==Universal Gravitational Distance: As the distance seperating two objects increase, the force of attraction is exponentially smaller.==

Coulomb's Law; = the relationship among electrical forces, charges and distances.

 * ==Electrical Field; A vector guantity that relates the force exerted on a charge to the size of the charge. The magnitude of the electric field is measured in N/C (Newtons/Coulomb)==
 * ==Electrical Lines: Direction of arrows indicate the charge of the lines.==
 * ==Grounding: Touching a body to earth to eliminate excess charge.==
 * ==Electric Current; Flow of charge particles. Current always flows from a higher potential difference (voltage) to lower potential difference. The flow will stop when the potential difference is zero.==
 * ==Electrical Energy Source; Voltaic or galvanic cells (dry cells) converts chemical energy to electrical energy.==

 * ==**Definitions**==
 * ==**Friction** is the force resisting the relative motion of solid surfaces, fluid layers, and/or material elements sliding against each other. It may be thought of as the opposite of "slipperiness".==
 * ==**Dry friction** resists relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into //static friction// between non-moving surfaces, and //kinetic friction// between moving surfaces.==
 * ==**Fluid friction** describes the friction between layers within a viscous fluid that are moving relative to each other.==
 * ==**Lubricated friction** is a case of fluid friction where a fluid separates two solid surfaces.==
 * ==**Skin friction** is a component of drag, the force resisting the motion of a solid body through a fluid.==
