Question
Answer
a system used to describe motion that gives the zero point location of the variable being studied and the direction in which the values of the variable increase   coordinate system  
🗑
the point at which both variables in a coordinate system have the value zero   origin  
🗑
the distance and direction from the origin to an object   position  
🗑
the entire length of an object's path, even if the object moves in many directions   distance  
🗑
a measure of size   magnitude  
🗑
a quantity that has both magnitude and direction   vector  
🗑
a quantity that has only magnitude, and no direction   scalar  
🗑
the difference between two times   time interval  
🗑
a change in position having both magnitude and direction; is equal to the final position minus the initial position   displacement  
🗑
a vector that represents the sum of two other vectors   resultant  
🗑
the position of an object an any particular instant   instantaneous postion  
🗑
the ratio of an object's change in position to the time interval during which the change occurred   average velocity  
🗑
the distance traveled divided by the time taken to tr4avel that distance   average speed  
🗑
a measure of motion that tells the speed and direction of an object at a specific instant   instantaneous velocity  
🗑
