how do you calculate speed
distance / time
what is the unit for speed
ms ^-1
how do you define speed
distance moved along the path divided by the time taken
what is relative speed
speed of an object as observed from the perspective of another moving object
how do you calculate relative speed in the same direction
∣v1−v2∣
how do you calculate relative speed in the opposite direction
v1+v2
how do you calculate velocity
displacement / time
