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
