Mission CG1: Speed and Velocity

Mission CG1 focuses on the concepts of speed and velocity as it pertains to the motion of an object in a circle. You should be able to describe the direction of the velocity vector and the variables affecting its magnitude.  The mission consists of 32 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...

Learning Outcomes

• The student should be able to distinguish between the concepts of speed and velocity and use such concepts to describe the motion of objects in a circle.
• The student should be able to identify and describe the direction of the velocity vector for an object moving in a circle and identify the variables effecting the magnitude of the velocity.

The Physics Classroom - Circular Motion Unit, Lesson 1, Part a

• Is speed a scalar or a vector? What about velocity?
• Can an object move with a constant speed and have a changing velocity?
• What is the direction of the velocity when moving in a circle?
• How does the radius of an object's circle effect the speed of the object?
• How are the radius of a circle and the period related to the speed?
