Speed, Velocity, Acceleration Reviewer

Scalar Quantity

Magnitude, No Direction, Only Numbers

Vector Quantity

Magnitude, Direction

Magnitude

a numerical value used to describe the size, quantity, or extent of a certain measurement

Reference Point

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

Distance

the total length of the path an object travels

Position

object’s distance and direction from the reference point

Two Dimensional

describe a position using two directions

One Dimensional

describe a position using one direction

Displacement

difference between the first position and final position of an object

meters per second

m/s

kilometers per hour

km/h

miles per hour

mph

Speed Formula

speed = distance/time

Time Formula

time = distance/speed

Distance formula

distance = speed x time

Speed Value

(unit of measurement)

Velocity Value

(unit of measurement) (direction)

Velocity, Displacement, Time

Acceleration Formula

acceleration = Vf - Vi/Tf - Ti = (Change)V/(Change)T
