is equal to the magnitude of the horizontal component of the projectile's acceleration. always decreases with time until the projectile hits the ground. is constant until the projectile hits the ground. In the absence of air resistance, the magnitude of the vertical component of a projectile's acceleration A. 'A' will reach the same height and have a shorter range than 'B'. 'A' will reach the same height and have the same range as 'B'. 'A' will reach a greater height and have a shorter range than 'B'. 'A' will reach a greater height and have the same range as 'B'. 'A' will reach a greater height and have a greater range than 'B'. Assuming level ground and negligible air resistance, which of the following is true? A. Projectile 'A' is fired at an angle of 50° above the horizontal projectile 'B' is fired with the same speed at an angle of 40° above the horizontal. To report the _ of an object, we must specify both its speed and its direction. The speedometer in your car tells you the _ of your car. It will hit the ground in more than three seconds at a speed greater than 12 m/s. It will hit the ground in less than three seconds at a speed less than 12 m/s. It will hit the ground in more than three seconds at a speed less than 12 m/s. It will hit the ground in less than three seconds at a speed greater than 12 m/s. It will hit the ground in exactly three seconds at a speed of 12 m/s. Which of these best describes its fate? A. 7.Ě bowling ball at a height of 36 meters above the ground is falling vertically at a rate of 12 meters per second. will have the same acceleration during each second of its fall. will have a constant velocity during each second of its fall. will have the same average speed during each second of its fall. will drop the same distance during each second of its fall.

What will be its speed after 2 seconds? A.Đ m/s B.ĕ m/s C.ē m/s D.Ė m/s E.Ē m/s 6.Ě body in free fall in a vacuum A.
acceleration D.Ě and B E.Ě, B, and C 5.Ě car initially at rest accelerates in a straight line at 3 m/s². If an object is moving, then the magnitude of its _ cannot be zero. an object at rest remains at rest unless acted upon by a net force. an object at rest always remains at rest. an object in motion moves in a parabolic trajectory unless acted upon by a net force.
an object at rest eventually begins to move. an object in motion eventually comes to a halt. 3.Ěccording to Newton's First Law of Motion, A. The property of a moving object to continue moving is what Galileo called A. The inertia of the book is equal to the inertia of the table. Table of Contents: Exam #1 - (motion, inertia, force, acceleration, etc.) Exam #2 - (momentum, work, energy, rotation, etc.) Exam #3 - (atoms, solids, liquids, gases, etc.) Exam #4 - (heat transfer, waves, sound, music, etc.) Exam #5 - (light, optics, electric charge, electric current, etc.) Lab Questions (for the Final Exam) AnswersĮxam #1 - (motion, inertia, force, acceleration, etc.) 1.Ě book is at rest on top of a table. James Pierce, Department of Physics and Astronomy, Minnesota State University, Mankato. Questions concerning this site should be directed to Dr. Those requiring more rigorous training may wish to examine a few more questions. The score on this sample exam should be a good predictor of performance on the real exam.
To get the maximum benefit from these questions, students should attempt to understand the terminology and concepts involved with each topic, rather than try to memorize the questions and their correct answers.Īfter studying the material for an upcoming exam, students should use these questions to prepare and take a sample exam. Instead they are meant to be a supplement to the rest of the course materials. These questions are not intended as a substitute for the text or the lecture notes. The table of contents indicates the topics to be covered on each of the first five exams.
Actual tests will contain some of these questions, variations on these questions, or related questions on the same topics.
