More Americans need to see your videos. Your simple, clear, coherent explanations coupled with your excellent use of high quality graphics and animations sets a new bar for what education should be. Keep up the amazing work!!!!
Hey @Mahesh Shenoy Sir, While Calculating Potential Energy Of Ruler When It Is Making Angle 90 Degree With Gravitational Field Line It Will Have Zero Potential Energy If We Use Our Formula U = PEcos90. But In Figure We Can Clearly See That It Has Potential Energy. Can You Please Explain How Is This Possible ?
it depends on the reference (the datum, or say the zero) with which you are measuring the potential energy. As we only measure the difference of potential energy, never its actual value.
0:01 0:15 0:25 why the stupid made up accent? lol... dont try to create/copy the Sal's style of hype/excitation. Just be yourself - like u were in -most- some other parts of the recording.
@@misc6412 i completely agree with you. It does not matter 🙄at all . The most important thing here is that he is giving such important piece of information with such clear visualisation and in a clear and understanding voice
