Work, energy, power and their relation with force.
Definition of work. W FS = cosθ; special
cases of θ = 00
, 900
. W= mgh. Definition of
energy, energy as work done. Various units of
work and energy and their relation with SI
units. [erg, calorie, kW h and eV]. Definition
of Power, P=W/t; SI and cgs units; other units, kilowatt (kW), megawatt (MW) and
gigawatt (GW); and horsepower (1hp=746W)
[Simple numerical problems on work, power
and energy].
(iv) Different types of energy (e.g., chemical
energy, Mechanical energy, heat energy,
electrical energy, nuclear energy, sound
energy, light energy).
Mechanical energy: potential energy U = mgh
(derivation included) gravitational PE,
examples; kinetic energy K= ½ mv2
(derivation included); forms of kinetic energy:
translational, rotational and vibrational -
only simple examples. [Numerical problems
on K and U only in case of translational
motion]; qualitative discussions of electrical,
chemical, heat, nuclear, light and sound
energy, conversion from one form to another;
common examples.

ENTIRE PLAYLIST OF PHYSICS ICSE CLASS 10 :

[kamojhalavikhyaat]

thanks a lot good explanation.... just entered 10th and still this one-year-old video is ever legends who r watching this video in 2024 before entering 10th

[azvindersandhu-buim]

My father went to duty and worked hard in office but came back to same house frome he was gone means his displacement is zero so, according to physics his work done is 0😢😢

[unknowngaming]

Legends watching the video in 1.5x speed😂😂😂

[anjnabarla]

This is the first time i find physics intresting. Hat's off to you sir 👍.you videos are so helpful. Thank you so much 🙏

[megamaugaming]

What is the meaning of the line,

The component of displacement in the direction of force is AB.(by finding component of displacement along the force)

[shreyanprasad]

3:19 Work is not done on pushing a wall.

[SangitaKumari-iuot]

If we apply a force and the wall does not move then there will be no work.

[adrikamishra]

Sir value of cos 90 is 0 but you wrote ∞(infinite) [8:27]

[priteshranjantiwari]

No sir if we apply a force on the wall and the wall doesn't move then there 3:40 will be no work done because there is no displacement

[shrutipandey]

Itna achaa channel abtak kaha tha yrrrr ye itna badhiya hai🎉🎉🎉🎉

[AnantKrishnaPandey-vely]

Your video is very helpful for me after 1 day my physics exam will be held now i am filling very confidence thank you dear sir.

[Archi_arena]

Your videos always help me for my studies sir🙏
Thank u so much sir for making each and every videos of icsc books

[killuaftw]

sir missing your sessions so much and now i am here rewatching feels so good❤

[anchalthakur]

Sir your teaching skill is amazing with little sense of humour ✨😭

[roopakn]

I only follow up you sir ❤ very good 💯 teaching, my concepts got cleared

[joblessblink]

Anybody who is watching this video on 1.25x speed

[neonxprgaming]

Keep smiling sir...a good person's smile is most valuable than anything

[snehakumari]

sir....How force against gravity and with gravity is same ? when a body is thrown up, gravity wants to pull that body down so (logically) more force is required and if a body falls down, gravity is acting with the body so even if no force or less force is applied then also the body will reach the ground ?

[PragyanKumar-wjlu]

sir is the work done by plane is also in negative as it is done against the gravity
