Scalars are quantities that take into account amount, not direction

Vectors are quantities that take into account direction

seconds

final position - initial position (xf-xi)

scalar does not take into account direction distance/t

vector displacement/t

speed

opposite way (go by absolute value)

does not take into account direction—> scalar

meters

Displacement takes into account the "net" distance traveled, therefore it is a vector quantity.

not lines not constant slope changing slope changing velocity

constant velocity

negative velocity

negative steep velocity

describes an object's change in velocity over a given period of time meters per second per second m/s/s m/s^2 vector

way of describing the motion of objects without describing the causes.

In words Mathematically Pictorially Graphically

Variable: Time Unit: s

Variable: acceleration Unit: m/s^2

Variable: Displacement Unit: m

variable: final velocity Unit: m/s

Variable: Initial Velocity Unit: m/s

Variable: acceleration due to gravity Unit: m/s^2

Givens [initial velocity counts as well], Unknown[what we're looking for], Equation, Substitute, Solve.

the object is speeding up

All are used when the acceleration is CONSTANT.

initial velocity is zero

final velocity is zero

no displacement final velocity

displacement no final velocity can be used to find distance
