kinematics

the study of motion of mechanical points, bodies, and systems

position

the location of an object at any time

physical quantity

length, mass, height; quantities that can be measured

scalar magnitude + quantity

time, mass, speed

vector magnitude

direction, velocity, acceleration

distance
