Speed = Distance / Time
Velocity tells you how fast an object is moving but also tells you the direction it is travelling in (m/s). It is a vector quantity.
Velocity(m/s) = Displacement (m) / Time (s)
Travelling Forwards = Positive Value Travelling Backwards = Negative Value
Displacement is like distance except from that it is a vector quantity, it also gives you the direction , therefore it can be positive or…
