Determine whether each phrase describes speed or velocity. the displacement of an object during a specific unit of time: how fast or slow an object is moving and in what direction: how fast or slow an object is moving: a cheetah running 97 km/h: a train traveling 45 m/s north:

The displacement of an object during a specific unit of time:  Velocity (the direction is part of displacement.)

How fast or slow an object is moving and in what direction: Velocity (speed & direction)

How fast or slow an object is moving:  Speed (no direction)

A cheetah running 97 km/h:  Speed (no direction)

A train traveling 45 m/s north:  Velocity (speed & direction)

what are the options.
