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 ...

• 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.

If you are not familiar with this topic, then you should first learn about the topic using our written Tutorial or our Video Tutorial:
 

• 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?
