Term

Definition
total path length from the starting point to end point, scalar quantity, symbol s, unit m 


Term

Definition
straight line distance from the starting point to end point (distance traveled in a particular direction), vector quantity, symbol s, unit m 


Term

Definition
distance traveled divided by the time elapsed, scalar quantity, symbol v, unit m/s 


Term

Definition
displacement traveled divided by time elapsed, vector quantity (direction same as displacement), symbol v, unit m/s 


Term

Definition
total displacement divided by the time elapsed 


Term

Definition
displacement per unit time at a particular point in time 


Term

Definition
when displacement per unit time is the same for every moment of time 


Term

Definition
change in velocity per unit time, vector quantity (may or may not have same direction as velocity), symbol a, unit m/s^2 


Term

Definition
when an object is thrown up, thrown down, or dropped 


Term
Newton's First Law of Motion: Law of Inertia 

Definition
a) a body at rest will remain at rest unless acted upon by an unbalanced or net force b) a body moving at uniform velocity will remain that way unless acted upon by an unbalanced or net force 


Term
Newton's Second Law of Motion 

Definition
an unbalanced or net force causes an acceleration which is directly proportional to the force and inversely proportional to the mass of the object, formula: Fnet=m*a 


Term

Definition
a push or pull applied to an object, a vector quantity (direction is the same as the direction of acceleration), unit is N, symbol F 


Term

Definition
the measure of the gravitational force acting on an object, formula: Fw=m*g 


Term
Newton's Third Law of Motion: ActionReaction 

Definition
if object A exerts a force on object B, object B will exert an equal but opposite force on object A 


Term

Definition
the object which exerts a force on the other 


Term

Definition
the object that exerts an equal but opposite force on the action force 


Term
Newton's Law of Universal Gravitation 

Definition
law that states that every object in the universe attracts every other object with a force which is directly proportional to the produce of their masses and inversely proportional to the square of the distance between their centers (approximately true when the objects are massive and far apart, absolutely true when objects are point masses), formula: Fg=(G*m1*m2)/s^2 (right side of formula comes to N) 


Term

Definition
a region of space around a mass in which another mass feels a force 


Term

Definition
1.0 kg mass used to test gravitational field 


Term
gravitational field strength 

Definition
the force felt by a 1.0 kg mass when place at a certain location in a gravitational field, vector quantity (direction is to the center of the celestial body causing the field), symbol g, at surface of earth g=9.8 N/kg 


Term

Definition
occurs for objects in free fall when the force of gravity pulling the object down equals the force of the air pushing the object up, Fnet=0, a=0, and the velocity is uniform
