Lutz, Joe; Sylvester, Kevin; Oliver, Keith; Herrington, Deborah – Physics Teacher, 2017
"For every action there is an equal and opposite reaction." "Except when a bug hits your car window, the car must exert more force on the bug because Newton's laws only apply in the physics classroom, right?" Students in our classrooms were able to pick out definitions as well as examples of Newton's three laws; they could…

Coletta, Vincent P.; Bernardin, Josh; Pascoe, Daniel; Hoemke, Anatol – Physics Teacher, 2019
Physics instructors recognize the value of kinesthetic experience in learning fundamental physics concepts. We describe a kinesthetic experiment appropriate for both college and high school physics students. The experiment helps students achieve an intuitive understanding of Newton's second law in a way they find quite enjoyable. It was devised by…

Scomparin, P. R.; Carvalho-Neto, J. T. – Physics Education, 2018
Newton's laws of mechanics are a cornerstone in the development of modern science and its learning can be the very first opportunity for students to defy their common sense perceptions and replace them with a more robust world view. However, despite their fundamental importance, many studies demonstrate how difficult is the true comprehension of…

McClelland, J. A. G. – Physics Education, 2016
Newton's first and second laws have implications for the kinetic energy as well as the momentum of a body. It is recommended that this should be made explicit at an appropriate point in a course.

Perea Martins, J. E. M. – Physics Education, 2018
This work describes a simple experiment to measure the resistor temperature as a function of the applied power and proves that it is an efficient way to introduce some important physical concepts in classroom, including the Joule's first law, hot-spot temperature, thermal resistance, thermal dissipation constant, time constant and the Newton's law…

Gangopadhyaya, Asim; Harrington, James – Physics Teacher, 2017
Newton's laws have engendered much discussion over several centuries. Today, the internet is awash with a plethora of information on this topic. We find many references to Newton's laws, often discussions of various types of misunderstandings and ways to explain them. Here we present an intriguing example that shows an assumption hidden in…

Low, David; Wilson, Kate – Teaching Science, 2017
On entry to university, high-achieving physics students from all across Australia struggle to identify Newton's third law force pairs. In particular, less than one in ten can correctly identify the Newton's third law reaction pair to the weight of (gravitational force acting on) an object. Most students incorrectly identify the normal force on the…

Fratiwi, Nuzulira Janeusse; Samsudin, Achmad; Ramalis, Taufik Ramlan; Saregar, Antomi; Diani, Rahma; Irwandani; Rasmitadila; Ravanis, Konstantinos – European Journal of Educational Research, 2020
The identification of students' mental models is crucial in understanding their knowledge of scientific concepts. This research aimed to develop a Mental Models Representation Instrument on Newton's Laws (MeMoRI-NL). The ADDIE (Analyzing, Designing, Developing, Implementing and Evaluating) model was used as a research method. The sample consisted…

Hill, Trevor; Hill, Lara – Physics Education, 2017
After many years of confusion, thermal performance of sleeping bags has now been quantified and unified using expensive test techniques. Based on Newton's law of cooling, we present a simple inexpensive test and model to check manufacturers' claims on the temperature performance of a range of modern sleeping bags.

Perea Martins, J. E. M. – Physics Education, 2017
This work presents a simple analogue waterproof temperature probe design and its electronic interfacing with a computer to compose a data acquisition system for water temperature measurement. It also demonstrates the system usage through an experiment to verify the water heating period with an electric heater and another to verify the Newton's law…

Pleasants, Jacob – Science Teacher, 2018
In classroom science laboratories, unlike a real science laboratory, the teacher can guide students away from potential dead ends and toward data that are most likely to result in accurate conclusions. Sometimes, though, allowing students to pursue dead ends and to collect "bad" data can provide especially rich learning opportunities.…

Galeriu, Calin – Physics Teacher, 2018
The recent use of Arduino Uno microcontroller boards for automated data acquisition has revolutionized physics education. The Arduino-based physics labs have dramatically lowered the cost of the experimental equipment, while at the same time replacing the commercial apparatus with open hardware and software. Students benefit greatly from rigorous…

Huggins, Elisha – Physics Teacher, 2018
Consider the fall of the apple that, by legend, hit Newton on the head. Instead of using this to introduce Newton's law of gravity, we will discuss the point of view that the fall of the apple was caused by a minuscule curvature of spacetime in the region surrounding Newton and the apple tree. We will calculate this curvature using concepts and…

Cross, Rod – Physics Teacher, 2018
The acceleration of a vehicle or a bicycle is commonly used in elementary physics courses to illustrate problems concerning Newton's laws of motion when friction forces are involved. The maximum possible acceleration is rarely discussed, although it is of interest to consumers and racing car enthusiasts, and it is sometimes questioned by students.…

Atasoy, Sengül; Ergin, Serap – Research in Science & Technological Education, 2017
Background: A substantial review study of concept cartoons reports that few studies have indicated their functions. For this reason, the present study illuminates the extent to which concept cartoon-embedded worksheets (through constructivist context) accomplish these functions in conceptual learning. Purpose: The purpose of the study is to…
