**Chapter 11 Pages 362-393**

**Chapter 11 Overview**

This chapter covers motion, speed, velocity, and acceleration. Students learn how to calculate speed and acceleration and learn to interpret both distance-time graphs and speed-time graphs. The concept of force is also introduced, including balanced and unbalanced forces and the force of friction.

**Chapter Goals- Students will be able to explain:**

__Chapter 11 S.1 Measuring Motion__

1. How is a frame of reference used to describe motion?

2. What is the difference between speed and velocity?

3. What do you need to know to find the speed of an object?

4. How can you study speed by using graphs?

__Chapter 11 S.2 Acceleration__

1. What changes when an object accelerates?

2. How do you calculate the acceleration of an object moving in a straight line?

3. How can a graph be used to find acceleration?

__Ch 11 S.3 Motion and Force__

1. What do scientists identify as the fundamental forces of nature?

2. What happens when there is a net force acting on an object?

3. What force always opposes motion?

4. Why is friction sometimes necessary?

5.
