## Learning Outcomes for Newton's Laws

The list below displays sample learning objectives for the unit on Newton's Laws. The various activities from the Lesson Plans have been organized by objective. This format of organizing The Physics Classroom's activities may be more useful to some teachers than the Lesson Plan format. It is worth noting that the activities identified below only include those activities included on the Lesson Plans and in the Pre-Built Task Tracker courses. Additional activities are referenced on the Teacher Notes page.

### 1. Newton's First Law

Make meaning of Newton's first law by relating balanced forces to the two possible motion states (at rest and constant speed) and describe the relationship between mass and inertia.

### 2. Balanced vs. Unbalanced Forces

Relate the motion that occurs (and its representation by words, dot diagrams, or kinematic graphs) to the relative size of the individual forces acting up on an object for both balanced and unbalanced force situations.

### 3. Newton's Second Law

Use Newton's second law to relate the acceleration to the net force and object mass and to predict the effect of varying net force and/or mass upon the acceleration of the object.
