Mission CG6: Newton's Law of Universal Gravitation

Mission CG6 contains questions that target your understanding of the law of universal gravitation and the variable that affect the gravitational forces between masses. 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 recognize key elements of Newton's law of universal gravitation.
• The student should be able to identify the variables effecting the force of gravity and predict the effect of alterations in these variables upon the force of gravity.
