Determine V1-V2.Ĥ) A 20 kg iron block is kept on a horizontal table. If the coefficient of friction between the wheels of a car and the road is 0.5, then what is the (i) optimum speed of the car to avoid wear and tear on its tires, and (ii) maximum permissible speed to avoid slipping?ģ) The velocity of an object is V1=8 m/s towards N and the velocity of a different object is V2= 6 m/s towards West. How long does the stone remain in the air?Ģ) A circular track of radius 100 m is banked at an angle of 30°. Physics Problems and Questions for School and Competitive Examinations and Testsġ) A stone is falling freely from rest and the total distance covered by it in the last second of its motion equals the distance covered by it in the first 3 seconds of its motion.
Physics Problems and Questions: Question Bank-Set Number 1 We are coming up with more numerical in the coming days, which will have harder sets as well. The Standard of these sets is MEDIUM (not so hard).

The first set (Set number 1) is being published on this post body itself and the rest of the sets (6 more) are being embedded in a pdf file, which is also available right on this page for you. These numerical problems and questions are distributed among 7 sets of Questions for you. Error bars represent the standard deviation of the mean.Here we are publishing a large number of physics problems and questions, with selective hints as well. A preprint version is available on the arXiv.Īverage exam scores for both the traditional and reformed sections. The published paper is available at the following link: Students Taught by a First-Time Instructor Using Active-Learning Teaching Strategies Outperform Students Taught by a Highly-Regarded Traditional Instructor. Because the final exam was a cumulative exam, this result suggests that the effects of active learning may be cumulative: As students spent more time actively engaged with the material, they experienced increased abilities to recall, apply, and synthesize what they learned, even in contexts that were prima facie novel. By the final exam, students of the first-time instructor were outperforming their peers by as much as two letter grades on some questions. These results held for both conceptual and quantitative questions. The results were dramatic: On almost every question on every exam, students of the first-time instructor outperformed students of the experienced instructor.
Peer Instruction) in a novel way during lecture to improve students’ problem-solving skills.
Additionally, the first-time instructor used the technique of Think-Pair-Share (a.k.a. During these breakout sessions, students worked collaboratively on activities informed by physics education research that were designed to improve student’s conceptual understandings and problem-solving skills. The first-time instructor sacrificed one of his three weekly lectures to make room for small breakout sessions of approximately 25 students each. Students in the two classes took identical exams. Their paper, which was just published in the Journal of College Science Teaching, describes a semester-long experiment comparing two introductory physics courses, one taught by an experienced and popular instructor who only lectured, and the other taught by a first-time instructor who made extensive use of active learning pedagogies.īoth classes enrolled over 200 students and covered the same content. A new paper by Colin Wallace, a Teaching Associate Professor in our Department, and his colleagues at the University of Arizona, reveals the extent to which an entire semester of active learning benefits students. It’s no secret that active learning helps students learn and retain more information than they would from traditional, lecture-only instruction.
