Vector

A quantity that has magnitude and direction

Scalar

A quantity that has magnitude and size

Distance

a scalar quantity that refers to "how much ground an object has covered" during its motion.

Displacement

A vector whose length is the initial distance minus the final distance (xi-xf)

Velocity

A vector measurement of the rate and direction of motion

Speed

Distance travelled per unit time

Unit

Meter,Kilometers,seconds ect.

Variable

Quantity whose value can change

V=d/t or velocity=distance / time

the velocity equals the distance divided by time

constant motion

v=displacement/time

acceleration

acceleration= delta velocity/time

xi

initial position

xf

finial position

🔺x

change in position

t

time
