# Chapter 3: Two-Dimensional Motion and Vectors

Scalars and Vectors

Vector Fundamentals

This video by an award-winning high school science teacher describes vectors and scalar using demonstrations and animations. The video concludes with a discussion, review, and problems. http://www.bozemanscience.com/science-videos/2011/1/28/scalars-and-vectors.html

(Objective: Distinguish between a scalar and a vector.)

Vector Components

A description and illustration of vector components.

(Objective: Add and subtract vectors by using graphical method.)

Vector Operations

A collection of animations that illustrate various vector operations using simple graphics.

(Objective: Add and subtract vectors by using graphical method.)

Two-Dimensional Motion

This simulation helps to visualize and explain motion, acceleration, and velocity. (Objective: Add and subtract vectors by using graphical method.)

Projectile Motion

The Monkey and the Zookeeper. An interactive game in which the student fires bananas at a monkey under different conditions, including fast speed projectiles and firing in a gravity-free environment. http://www.physicsclassroom.com/mmedia/vectors/mzi.cfm

(Objective: Describe the path of a projectile as a parabola.)

Relative Motion

Relative velocity is illustrated using an animation of airplanes in flight. Students may change certain of the conditions of each flight to see different outcomes.

(Objective: Solve problems involving relative velocity.)

Relative Motion flash animation of a boat on a river. You adjust conditions to change the movement of the boat. http://research.physics.illinois.edu/per/Flash/relative_motion_mls.swf

(Objective: Solve problems involving relative velocity.)
