Question

velocity
to describe the motion of an object, you need to know more than just its speed. velocity is the speed at which an object travels in a given direction.

1. what is different about these two trains? explain how this describes speed and velocity.

type your answer here.

Explanation:

The two trains have the same speed ($80$ km/h) but different directions (one west, one east). Speed is just a magnitude. Velocity includes both magnitude (speed) and direction. So, while their speeds are equal, their velocities are different because of the opposite directions.

Answer:

The two trains have the same speed ($80$ km/h) but different directions (west and east). Speed is a scalar (only magnitude), velocity is a vector (magnitude + direction). Here, same speed but different velocities (due to direction).
