Teaching guide, sample answers and curriculum references

Before you begin

Read or listen to the model and identify what the task asks before responding.

How to use this worksheet

  1. Find the signed net force in newtons.
  2. If both forces double with the same mass, what is the new acceleration?
  3. Does acceleration direction alone establish the current velocity direction?

A common mistake to discuss

No. An object can move left while accelerating right and slowing down.

What to practice next

Create a different example that preserves the learning goal, and explain how you would check it.
