physics - 1.3 position, displacement, velocity, acceleration

position

location of an object relative to an origin

displacement

delta x, change in position, x final - x initial, vector

average speed =

distance/change in time (m/s)

average velocity

displacement/change in time (m/s)

speed vs velocity

speed gives you a magnitude while velocity gives you a magnitude and direction

average acceleration =

change in velocity/change in time (m/s²)
