Mass and Weight - Questions

The Mass and Weight Concept Builder is comprised of 28 questions. The questions are divided into 9 different Question Groups. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three Activities by which the student can progress through the Concept Builder. Those three Activities are summarized as follows:
 

• Two Truths and a Lie: Question Groups 1-4 Students pick the False statement from among three statements.
• Calculate It!: Question Groups 5-8 Students perform straight-forward calculations of mass and weight from given information.
• Out of This World: Question Group 9 Students pefrom calculations of mass and weight in order to complete a 7-row table that includes locations other than Earth.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activity is most appropriate for their classes. We recommend providing students two or more options. 

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.

Question 3
Consider the following three statements. Two are true and one is false. Identify the false statement.
 
More massive objects experience a greater force of gravity than less massive objects.
