warm-up
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:

Explanation:

• Speed is a scalar quantity that only describes how fast or slow an object is moving (e.g., "A cheetah running 97 km/h").
• Velocity is a vector quantity. It describes both how fast or slow an object is moving and its direction (e.g., "The displacement of an object during a specific unit of time", "How fast or slow an object is moving and in what direction", "A train traveling 45 m/s north").

Answer:

1. Velocity
2. Velocity
3. Speed
4. Speed
5. Velocity
