A video podcast for high-school students studying physics. Home page: http://www.ibphysicshelp.net
This episode is an introduction to electromagnetic induction. The presentation is supported by many experimental demonstrations. The video covers the following topics: 1. Oersted’s discovery of the magnetic effect of an electric current (sometimes called the “motor effect” as it is the principle behind simple DC motors); 2. Faraday’s discovery of electromagnetic induction; 3. Magnetic flux; 4. Flux linkage; 5. Faraday’s law of electromagnetic induction; 6. Lenz’s law (or Lenz’s rule); 7. Eddy ...
Topics covered in this episode: (a) The period of a gravitational pendulum (b) Using a gravitational pendulum to determine the acceleration due to gravity, g, (c) Measuring mass using harmonic oscillators, (d) Energy in SHM, (e) Connection between SHM and uniform circular motion.
This video is an introduction to simple harmonic motion (SHM). SHM is a type of periodic motion for which the force that drives it is proportional to the displacement from the equilibrium position. What is the equation that describes this type of motion? The answer and more in this episode. This first part covers the basics of SHM. The second part (a separate video, Episode #8) covers, amongst other things, some practical applications of SHM.
What is the purpose of plotting various graphs for moving bodies? How are quantities like displacement, velocity and acceleration calculated from graphs of motion? This podcast covers the three main types of graphs: displacement-time, velocity-time and acceleration-time graphs.
The topic of this episode is Uniform Motion. What is an equation of motion? How does the equation of motion looks like in the specific case of uniform motion? How do we use equations of motion in solving problems? The answers, with examples, in this episode.
Uniform motion, uniformly accelerated motion, uniform circular motion, simple harmonic motion - what is the difference between all these types of motion? This episode presents a simple classification of the most common types of motion that one might come across when studying physics in high school.
