Physics Explained: Work, Energy & Power | Part 1: Work Done

[@maryamelleathy7590]

Never came across a video that explains a concept so thoroughly. You explained the thought process behind answering, the reasoning behind each step, and worked through the exercises with us which is exactly what I was looking for and needed to fully understand. Thank you kind sir. Your work is really appreciated.

[@MlungisiNkosi]

I sincerely appreciate your comment. I can’t wait to hear you say “Sir I got a distinction”

Everyone knows u at my school that how much u r helping us . At some point I hated attending physic class but after watching your videos ,I now have hope

Dude, I went from not understanding 1% ot the work to fully understanding it all. Very good teacher.

You guessed right 🤣🤣. To be honest, as soon as I heard your greeting I knew that I would understand the concept more than I ever did with previous videos I watched. I am currently doing B.ed and its my first year, but the way you explained this concept it is definitely the similar if not the same way I'll be explaining this concept once I become a certified teacher. Thanks a lot for making me understand this way more than I ever did🙏🏾🙏🏾✔✔

[@UthixunamHewu__]

This made sooo much sense, thank you so much😩 Question: I see when you write the formula for example at the inclined plane, 3rd question to find the gravity, this question is basically for all the questions but I'm going to use that one as reference, I noticed how you write it as: Wg//=Fg//.change in x.cos of angle I write as: W (Fg// as a subscript since it's the work by that component) =F (Fg// again as subscript). change in x.cos angle Does it matter how you reference it? I'm asking mainly because my physics teacher at school does not mark the rest of the sum if one's formula is incorrect so I'm making sure of finer detail...
