Describing Motion

Vocabulary

QuestionAnswerFormula
The process of changing position. Motion *An object is in motion if the distance between the object and a reference point is changing
A distance from starting point to final point. Displacement Distance= x + y
A length of the path taken. Distance Displacement= C^2=A^2+ B^2
A measure of the distance an object travels per unit of time. Speed Speed= distance/time Distance= Speed * Time Time= Distance/Speed
The speed and direction of a moving object. Velocity Velocity= distance/time Distance= Velocity * Time Time= Distance/Velocity
The rate of change of position in which the same distance is traveled each second. Constant speed
An object's speed at a specific instant in time. Instantaneous speed
The total distance traveled divided by the total time taken to travel that distance. Average speed Average speed= total distance/total time
A measure of the change in velocity during a period of time. Acceleration Acceleration= final speed - initial speed/total speed a=v2 - v1/t
The starting point you use to describe the motion or the position of an object. Reference point
An object's distance and direction from a reference point. Position
