Question

1. two - dimensional motion

what was the old view of two - dimensional motion?

what was galileos new view?

what analogy did galileo use to explain this?

Explanation:

The old - view of two - dimensional motion considered motions in different directions as interfering with each other. Galileo's new view was that two - dimensional motion could be analyzed as two independent one - dimensional motions. He used the analogy of a ball rolling off a table, where the horizontal motion of the ball (constant velocity if no friction) and the vertical motion (free - fall under gravity) are independent of each other.

Answer:

1. Old view: Motions in different directions interfere with each other.
2. Galileo's new view: Two - dimensional motion is composed of two independent one - dimensional motions.
3. Analogy: A ball rolling off a table with independent horizontal and vertical motions.
