Mission CG2: Acceleration and Net Force

Mission CG2 focuses on to the concepts of acceleration and net force and how they pertain to an object moving in a circle. You should be able to identify the direction of these two vectors for an object moving in a circle at a constant speed. The mission consists of 36 questions organized into 9 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 recognize that objects moving in circles have an acceleration and explain the cause of this acceleration.
• The student should be able to describe the magnitude and direction of the acceleration and net force vector of an object moving in a circle at a constant speed.
