## Lab 2.2 Newton's Second Law Lab - by AP Physics (20 points)

**Question**:

How is acceleration affected if either the mass of the system or the force used to pull the bike changes?

**Purpose**:

In this lab students investigate how the acceleration of an object is related to its mass and the force exerted on the object, and use their experimental results to derive the mathematical form of Newton’s second law.

**Science Practices:**

- 1.1 The student can create representations and models of natural or man-made phenomena and systems in the domain.
- 4.1 The student can justify the selection of the kind of data needed to answer a particular scientific question.
- 4.3 The student can collect data to answer a particular scientific question.
- 5.1 The student can analyze data to identify patterns or relationships.
- 5.3 The student can evaluate the evidence provided by data sets in relation to a particular scientific question.

Newton’s second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. That is, F = ma .

This lab is designed to explore this relationship between mass and acceleration in systems with multiple objects of multiple weights.
