## Reflection: Complex Tasks Applying Newton's Second Law Quantitatively - Section 4: Students Practice 2nd Law Problems

Because of the scaffolding that has happened in the previous problems (calculating net force, drawing simple FBD) I find that most students are able to complete most of these problems independently. A student work - exemplar and solution shows successful completion of this worksheet. This can be used as the solution sheet.

There are often some pieces that students miss such as the force of gravity and the normal force or they might add forces when they should have subtracted forces because they are acting in opposite direction. Students are expected to fix these mistakes, as can be seen in this student work example, when we review this sheet as a class the next day.

# Applying Newton's Second Law Quantitatively

Unit 1: Forces in One Dimension
Lesson 5 of 11

## Big Idea: The acceleration of an object is always in the direction of the net force acting on it.
