Front

Back

elapsed time

Front

the difference between the ending time and the beginning time

Back

instantaneous speed

the absolute value of the instantaneous velocity |v(t)|

Back

instantaneous velocity

the velocity at a specific instant or time point

Back

total displacement

Front

the sum of individual displacements over a given time period

Back

average acceleration

Front

the rate of change in velocity; the change in velocity over time

Back

reference frame

Front

coordinate system in which the position, velocity, and acceleration of an object at rest or moving is measured

Back

distance traveled

Front

the total length of the path traveled between two positions

Back

position from velocity and acceleration

Front

constant acceleration

Back

velocity vector

Front

vector that gives the instantaneous speed and direction of a particle; tangent to the trajectory

Back

average speed

Front

the total distance traveled divided by elapsed time

Back

free fall

Back

kinematics

Front

the description of motion through properties such as position, time, velocity, and acceleration
