The following practice questions test your understanding of the graphical description of motion. Use the Show Answer! button to view answers and explanations. Further information is available on-line at The Physics Classroom Tutorial.

NOTE to the Student:
There is a lot of information on this page. It is suggested that you first read the questions and make efforts to answer all the questions before peeking at the answers. Once you've answered all the questions, then check your answers. Physics is learned most effectively when your mind is actively engaged in the processes of analyzing and predicting. Avoid treating the information on this page as factual information to be dumped inside of a mental receptacle. Avoid merely looking at the answers; take the time to study the logic of the answers. If still unclear, consider online help at The Physics Classroom Tutorial or see your teacher for further assistance.
