Physics of Work, Power & Energy (AP Physics, IIT JEE, NEET)

This physics course includes 25 videos totaling 2.5 hours of run time that you can learn online. Get a deep understanding of physics of-

• Work done by a force – In physics, work and energy can get confusing if not understood at a conceptual level. This lesson introduces you to this in a very simple way and lays foundation of this topic

• What exactly is negative and positive work – Is it confusing to find when is work done by a force negative or positive? It indeed can be. Learn in this chapter how the dot product of force and displacement can give you the value of work done by the force and also if it is negative or positive.

• Work kinetic energy theorem – Change in kinetic energy can be equated with the work done on the body. This is often expressed as the work kinetic energy theorem and is one of the most popular theorems in physics. Watch this lesson to understand how you can use this theorem to solve a lot of numerical problems.

• Work done by gravitational force and spring force – What is the work done by gravitational force on a body?  The simple answer is the dot product of force and displacement. This physics video lecture explains how this force actually does work on a body, negative or positive. The lesson also explores the work done when a mass is lifted up and brought down. This is explanation has been done using work energy theorem. It also explains why using this theorem is better than using Newton’s laws of motion (often used in physics) in solving certain kinematic problems

• Work done by a variable force – spring force is a good example of defining what is work done by a variable force. For this spring this force F = -kx where the force varies as a linear function of displacement x. So far you have been finding work done by a force as a dot product of force and displacement where the force is constant. So this is an interesting lesson in the sense that here we will be dealing with forces that are variable in nature and how we can find work done by this variable force when it displaces a mass. We use differential calculus and integral calculus to establish this formula of physics

• What is average power and instantaneous power – The formula for work done = dot product of force and displacement. However, this assumes a constant force F on a particle. What then is work done by a variable force. Watch this lesson to understand how integral calculus can help us find the work done when the force acting in a particle is variable. You may like to draw comparison with an earlier physics lesson on velocity and instantaneous velocity

• What are conservative forces – What is a conservative force and how do you determine the work done by it, is an interesting relation between the work done by such a force and the potential energy and kinetic energy of a particle

Whats different about my courses:

When I create content for physics lessons, I think deeply around the areas where students struggle and feel confused. My lessons tackle these parts in depth. Also, I believe visual representation of various ideas makes a lot of impact. The lessons have visuals and animations that are thought through quite deeply

And most importantly, I make myself available personally to answer questions that a student who has enrolled may have

…and this is what my students wrote to me

Csaba:                                        I learned new ideas of approaches. I’m looking to try them in my professional practice as a teacher.Thanks! 🙂

Bobbie Smith:                           Amazing explanations, I really learned a lot. Thank you.

Satyam Jha:                               amazing!! i could not understand vectors in my class but here it is very easy to understand Thanks a lot!!

Fernando  P. Radaza:              It help me a lot to understand better about Physics of Work, Power & Energy.

Chamara Dilshan:                    it’s good, explaining every small thing ,it’s good to start physics beginners

Onofrio :                                   The lessons given by the teacher are very interesting! Excellent course!

Simaran:                                    Very deep understanding of the subject

Shiva:                                          Very knowledgeable and sounds very nice and helpful

Gallina:                                       Excellent the lessons held by the teacher with exhaustive explanations and well illustrated. Well done course! Smith:                                         Great course.The presentation is very clear. Thank you.

Pawan Kumar:                         The way to teaching us is amazing with all diagrams

Samit                                          This course has a lot of good content and very well presented. Thank you

Dani:                                            It was concise and consequent. The exercises were good exposed and explained. Simply excellent. I promise, that i will use some ideas in my every day practice in my classroom. I’m also teaching physics, but in Hungarian. I finished this course to improve my skills, first of all in interesting approaches, and foreign language skills as well. This course was exactly what I expected!
