Hi guys,

In this video we cover the topic of energy, work and power. We will aim to cover:
- Types of energies
- Calculating gravitational and kinetic energy
- Work and power

Hey man, ive been watching your channel since last year whilst preparing as a homeschooled student for the IGCSE. These have helped me so much, I wrote the O/N series and got an A* in Physics and an A in chemistry. Thank you for your help. If you could, please make AS Level videos as well!!

[terabaapaaya]

Seriously bro you are a life saver❤️❤️ You explained everything my class studied for 2 months in 15mins

[solehazikri]

THIS IS 100% HELPFUL, VERY HELPFUL, now I know how to do the calculating

[hamzafaheem]

i have my combined science exam tomorrow, thank you!

[mahdikhan]

Bro, you are a Helpful person... We must respect your Work.

[interestingrepublik]

Man, your videos are great. Your explanation makes the topic so much easier. Hats off to you!

[weatheredge]

the fact that you are a llegend saved me my midterm exam is tommorow

[gamingtechproductions]

I watched your videos in my igcse they were great can u also make AS level videos

Quick Question: why don't we count the weight of the object in the work?

[lixa]

your videos are really helpful..thanks a lot! btw i can find notes of work and power on your website!

[nx]

i have a question if energy is never created or destroyed where did it come from

[huzaifahameed]

U can remeber the power formula by this : if u want a lot of power u would need to put work over time

Question: Why do we need to write both an equation for the lorry and car when they're both equal. Cant we just do the calculation for the lorry and since the KE for the lorry is equal to the KE for car, the answer would be 32000 too? Can you please explain it to me if you don't mind.

[InnovativeJoy]

can anyone explain how in the first example he got 16 cuz if im not wrong 14 squared is like 196 or smth so im a lil confused

[obuilemore]

im sorry but i dont quiet understand why you said 2000 *16 in your example for kinetic energy

[felixknowloveyoudlovetokno]

with due respect, is this outdated? i believe energy can be seen as being created, i may be completely wrong.

[geopolitics]

but i didnt understand the last q ii part

[Taha-lr]

u sound like as if u spat in ur mic, no offense
