Introductory physics

teaching assistant, I conducted labs, discussion sessions, and some honor sessions for introductory physics courses in electromagnetism, thermal dynamics, optics, and modern physics. As a project assistant, my responsibilities included grading homework, discussing it with students, and prepare some homework solutions in quantum mechanics, quantum field theory, and an introductory physics course. In teaching physics, my main goal is to have my students actively thinking like physicists. I believe that

Problem of Problem Solving A common claim for the benefits of students taking introductory physics classes is that students are taught essential problem solving skills. The skills that students learn in these classes can be transferred, thus enabling them to be better problem solvers across the board. Is this truly what is happening, though? Unfortunately, students’ thought processes in general about solutions to physics problems is entirely formula-centered with the objective being to determine some

Maximum Safe Velocity Scenario 1 The two forces acting on the car when it turns a circular path are centripetal force, FCP , and friction, Ff . As mentioned in Relevant Physics Topics, the direction of friction opposes the direction of motion, which, in this scenario, is centripetal force, and because centripetal force directs towards the center of the circle, friction directs outside of the circle (Madden et al., 2001). To calculate the safe cornering speed on a level road, centripetal force has

The Physics of Team Fortress 2 Research and Presentation AP Physics 1 Carlos Arias Paradise Valley High School 5 December 2016  Abstract Arthritis is a medical condition that causes joint inflammation, stiffness, and resulting pain. This disease affects an estimated 40 million Americans, with a positive correlation towards old age. Opening medication bottles can be difficult for arthritis patients who struggle to open twist lids, snap lids, and click-locks. Janet Kramer is an arthritis patient

Basic Concepts Issac Newton was the first to state the concepts that are necessary to understanding the physics of collisions. His three laws are used again and again in all the fields of physics: Newton's 1st Law In the absence of external forces, an object at rest remains at rest and an object in motion remains in motion with a constant velocity. This law can be best observed in space, far from the gravity of a star or planet, where there is no friction or air resistance. If, in the

The photographs on the previous page were taken at Wild Walls Climbing Gym in Spokane, Washington. Photo #1 exhibits a climber while on the rock wall, supporting his own weight. Photo #2 displays the system employed by rock climbers to stay safe in the case of a fall. Two photos were taken in order to compare the system while the climber is on the wall and ascending against when the climber has fallen off the wall and is hanging by the rope. In the sport of rock climbing, the goal is, obviously

Math in Roller Coasters The main elements in creating roller coasters are physics and geometry. Geometry is a branch of mathematics with the properties and the relations of points, lines, surfaces, and solids. Speed is to move exceedingly fast, at different rates. Math is used to calculate the height of roller coasters. Engineers calculate the perfect angles, heights, and the directions that allow roller coasters to reach speeds without going off the track. They use some machines to test the roller

Aside from being one of the most accessible (and best!) sports out there, many aspects of bowling can be expressed with physics. Achieving maximum power, throwing a hook ball, and getting good pin action can all be broken down into physics issues and represented with equations. I will cover four aspects of bowling that can be explained with physics terms and show you how to use this knowledge to optimize your game. Gravitational Potential Energy Depending on the height from which the bowler

WORK and ENERGY Work done by a constant force 1- The drawing shows a plane diving toward the ground and then climbing back upward. During each of these motions, the lift force acts perpendicular to the displacement , which has the same magnitude, 1.7 × 103 m, in each case. The engines of the plane exert a thrust , which points in the direction of the displacement and has the same magnitude during the dive and the climb. The weight of the plane has a magnitude of 5.9 × 104 N. In both motions

Grid frequency $f$ can be considered as an indicator for system generation and consumption power balance, when an imbalance occurs the power system frequency will change accordingly. One of the responsibility's of a transmission system operators is to operate the electric grid at a certain system frequency which is the nominal grid frequency $f_{0}$, 50 Hz in Europe, where the torque is continually adjusted to keep the system frequency at the nominal grid frequency. in equation (1) Where $Tgen$
