Term Definition
Sir Isaac Newton English mathematician and physicist
Galileo Italian astronomer and mathematician who was the first to use a telescope to study the stars
Aristotle A Greek Philospher, taught Alexander the Great, started a famous school, studied with Plato
friction A force that opposes motion, resulting from the contact of two surfaces
Newton's First Law Law of inertia; An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force.
Newton's Second Law F=ma; When an object is acted on by one or more outside forces, the vector sum of those forces is equal to the mass of the object times the resulting acceleration vector.
force A push or a pull exerted on an object in an effort to change that object's velocity
SI System that contains the standard metric units used in science
Newton The SI unit of force, which is a [kg*m]/sec²
dyne A unit of force, which is a [g*cm]/sec²
mass A measure of how much matter is in an object
weight A measure of the strength which gravity pulls on an object
g a unit of force equal to the force exerted by gravity
slug The English unit for mass
pound The English unit for weight, which is a [slug*ft]/sec²
gravity the force of attraction between all masses in the universe
normal force A force that results from the contact of two bodies and is perpendicular to the surface of contact
kinetic friction Friction that opposes motion once the motion has already started
static friction Friction that opposes the initiation of motion
coefficient of friction A number (usually less than 1) that is used to calculate the force due to friction, It depends on the object in question and the surface upon which the object rests or moves.
coefficient of static friction The coefficient of friction used when an object is at rest.
coefficient of kinetic friction The coefficient of friction used when an object is already in motion.
frictionless lacking all friction
Newton's Third Law For every action, there is an equal and opposite reaction.
