Objectives – What is to be accomplished in this unit? - Study Guidelines

Chapter 4 - Newton’s First Law

Describe Aristotle's concepts of natural motion and violent motion.
Describe Copernicus' idea about the earth’s motion.
Describe Galileo's contribution to the science of motion.
State Newton’s first law of motion.
Distinguish among mass, volume, and weight, and their units of measurement.
Explain how something that is not connected to the ground is able to keep up with the moving earth.
Explain why a clothesline or wire that can easily support an object when strung vertically may break when strung horizontally and supporting the same object.
Describe how the angle between vectors affects their resultant vector.

Chapter 5 - Newton’s Second Law

State the relation between acceleration and net force.
State the relation between acceleration and mass.
State and explain Newton’s second law of motion.
Describe the effect of friction on a stationary and on a moving object.
Distinguish between force and pressure.
Explain why the acceleration of an object in free fall does not depend upon the mass of the object.
Describe the effect of air resistance on a falling object.

Chapter 6 - Newton’s Third Law

Define Force as part of an interaction.
State Newton’s third law of motion.
Given an action force, identify the reaction force.
Explain why the accelerations caused by an action force and by a reaction force do not have to be equal.
Explain why an action force is not cancelled by the reaction force.
Describe the horse-cart problem.
Explain why you cannot touch without being touched.

State Standards and Benchmarks Addressed by this unit.

P.1.7	Use Newton's Laws (e.g., F = ma) together with the kinematic equations to predict the motion of an object.
P.1.2	Measure or determine the physical quantities including mass, charge, pressure, volume, temperature, and density of an object or unknown sample.
P.2.1	Explain that Isaac Newton created a unified view of force and motion in which motion everywhere in the universe can be explained by the same few rules. Note that his mathematical analysis of gravitational force and motion showed that planetary orbits had to be the very ellipses that Johannes Kepler had proposed two generations earlier.
P.2.2	Describe how Newton's system was based on the concepts of mass, force, and acceleration, his three laws of motion relating to them, and a physical law stating that the force of gravity between any two objects in the universe depends only upon their masses and the distance between them.
