Acceleration

• a measure of the distance an object travels per unit of time

• speed at a specific instant in time

• a measure of the change of velocity over a period of time

• an object's distance and direction from a reference point

Displacement

• the starting point you choose to describe the location, or position of an object

• the process of changing position

• the rate of change of position in which the same distance is traveled each second

• the difference between the initial (first) position and the final position

Reference Point

• an object's distance and direction from a reference point

• the starting point you choose to describe the location, or position of an object

• the total distance traveled divided by the total time taken to travel that distance

• the speed and direction of a moving object

Position

• an object's distance and direction from a reference point

• the process of changing position

• the starting point you choose to describe the location, or position of an object

• speed at a specific instant in time

Motion

• a measure of the distance an object travels per unit of time

• the speed and direction of a moving object

• the rate of change of position in which the same distance is traveled each second

• the process of changing position

Constant Speed

• a measure of the distance an object travels per unit of time

Average Speed

• speed at a specific instant in time

• the total distance traveled divided by the total time taken to travel that distance

• the speed and direction of a moving object

• a measure of the change of velocity over a period of time

Velocity
