This page contains a full lab procedural on the topic of Newton's First and Third Laws of Motion and force-motion-vector diagrams. Special attention is focused on the "touch-body" diagram of representing motion. The lab, appropriate for introductory physics, is intended for use in cooperative learning groups. Socratic Dialog-Inducing (SDI) Labs are "guided construction" labs featuring hands-on experiments in introductory mechanics. They are carefully designed to promote the Socratic Method of inquiry, in which oppositional viewpoints are openly discussed to stimulate rational thinking. The contradictory view is often presented by a master teacher or, in this case, by the author of the lab manual. The effectiveness of this method in promoting student crossover to the the Newtonian World has been demonstrated by rigorous pre-post testing.

Determine the central ideas or conclusions of a text; summarize complex concepts, processes, or information presented in a text by paraphrasing them in simpler but still accurate terms.

Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 11—12 texts and topics.

Analyze how the text structures information or ideas into categories or hierarchies, demonstrating understanding of the information or ideas.

Evaluate the hypotheses, data, analysis, and conclusions in a science or technical text, verifying the data when possible and corroborating or challenging conclusions with other sources of information.

By the end of grade 10, read and comprehend science/technical texts in the grades 9—10 text complexity band independently and proficiently.

Make sense of problems and persevere in solving them.

Represent and model with vector quantities.

(+) Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes (e.g., v, |v|, ||v||, v).

(+) Solve problems involving velocity and other quantities that can be represented by vectors.

Perform operations on vectors.

(+) Add and subtract vectors.

Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum.

Interpret the structure of expressions

Interpret expressions that represent a quantity in terms of its context ?

Interpret parts of an expression, such as terms, factors, and coefficients.

Understand solving equations as a process of reasoning and explain the reasoning

Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.

Construct and compare linear, quadratic, and exponential models and solve problems

Distinguish between situations that can be modeled with linear functions and with exponential functions.

Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.

Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.

Interpret expressions for functions in terms of the situation they model

Interpret the parameters in a linear or exponential function in terms of a context.
