Chapter Overview

Our main purpose in this chapter is to explore how objects move under the influence of gravitational acceleration near the Earth's surface.

Chapter Outline

1. Acceleration due to gravity.How does a dropped object move under the influence of the Earth's gravitational pull? How is its acceleration measured, and in what sense is it constant?
2. Tracking a falling object.How do velocity and distance traveled vary with time for a falling object? How can we quickly estimate these values knowing the gravitational acceleration?
3. Beyond free fall: Throwing a ball upward.What changes when a ball is thrown upward rather than being dropped? Why does the ball appear to hover near the top of its flight?
4. Projectile motion.What determines the motion of an object that is fired horizontally? How do the velocity and position of the object change with time in this case?

CHAPTER 4:Newton's Laws: Explaining Motion

Chapter Overview

The primary purpose of this chapter is to explain Newton's three laws of motion and how they apply in familiar situations.

Chapter Outline

1. Newton's first and second laws.How do forces affect the motion of an object? What do Newton's first and second laws of motion tell us, and how are they related to each other?
2. Mass and weight.How can we define mass? What is the distinction between mass and weight?
3. Newton's third law.Where do forces come from? How does Newton's third law of motion help us to define force, and how is the third law applied?
4. Applications of Newton's laws.How can Newton's laws be applied in different situations, such as pushing a chair, skydiving, throwing a ball, and pulling two connected carts across the floor?

CHAPTER 5:Circular Motion, the Planets, and Gravity

Chapter Overview

Using the example of a ball on a string, we first examine the acceleration involved in changing the direction of the velocity in circular motion (centripetal acceleration). Next, we consider the forces involved in producing a centripetal acceleration in different cases, including that of a car rounding a curve. Newton's law of universal gravitation will be introduced to explain the motion of the planets. We will also show how this gravitational force relates to the weight of an object and the gravitational acceleration near the Earth's surface.

Chapter Outline

1. Centripetal acceleration.How can we describe the acceleration involved in changing thedirectionof an object's velocity? How does this acceleration depend on the object's speed?
2. Centripetal forces.What types of forces are involved in producing centripetal accelerations in different situations? What forces are involved for a car rounding a curve?
3. Planetary motion.How do the planets move around the sun? How has our understanding of planetary motion changed historically? What are Kepler's laws of planetary motion?
4. Newton's law of universal gravitation.What is the fundamental nature of the gravitational force, according to Newton? How does this force help to explain planetary motion?

CHAPTER 6:Energy and Oscillations

Chapter Outline

1. Simple machines, work, and power.What is a simple machine? How does the idea of work help us to understand the operation of simple machines? How do physicists define work, and how is work related to power?
2. Kinetic energy.What is kinetic energy? When and how does work change the kinetic energy of an object?
3. Potential energy.What is potential energy? When and how does work change the potential energy of an object?
4. Conservation of energy.What is the total energy of a system, and when is it conserved? How can we use these ideas to explain the motion of a pendulum and other phenomena?
5. Springs and simple harmonic motion. How is the motion of a mass on a spring-like pendulum? What is simple harmonic motion?
