Gravitational Potential Energy, Example Problems

Gravitational potential energy is the energy stored in an object due to its position. An objects gravitational potential energy is dependent on the object's mass and its height above a reference surface.

The SI unit for potential energy is the joule. Named after James Prescott Joule.

I am using step-by-step science alongside my course in Environ management. It's really helpful, thanks.

Hi! Could you solve some gravitational potential energy but with angle.

[koreenadeleurme]

Dang what an eye opener so cool you solved my major problem

[lilakohis]

it funny how a problem can become so easy when shown HOW TO USE IT. thank you!

[MarimeAzur]

Thanks for this it took me 3 days to figure this shit out my teacher just hands us papers without explaining helpful ✨🖤

[selvavinothinimuthukrishna]

sir, it was so helpful, please upload video on solving many examples of potential energy sums and work done related sums in gravitation chapter

[elviradanggoec]

Thank you very much. It help me solve my assignment

[Aimenxo]

Sir, can you please help me distinguish, when I make "g" sign negative and when it be positive?? Isn't it acceleration due to gravity and it is negative because gravity pulls down? I'm confused.. Please help me

Can you do the triangle things for all topics because I often struggle with rearranging equations

[arabbombergirl]

Thank youuu, I completely understand it now!☺️

I''m looking for an error in my calculations or my understanding of potential energy. Given: A Mg 3 meters high has a potential energy of 29, 400 J. 1000 kg · 9.8 · 3 = 29, 400 J. 1 J = 1 Ws. J / 3, 600, 000 = kWh. So, 29, 400 / 3, 600, 000 = 0.00817 kWh. An AA 1.2 volt battery with a rating of 2800 mAh has 3.36 Wh of energy. 1.2 V · 2.8 Ah = 3.36 Wh. 3.36 Wh = 0.00336 kWh. 0.00336 · 3 = 0.01008. Therefore 3 AA batteries contain enough energy, assuming 100% efficient power transfer, to raise a metric tonne 3 meters. I can not get my head around this idea. What am I unaware of that makes this scenario seem ridiculous to me?

I need help my test is tomorrow!! Where does the 9.81m/s2 come from in the first question?!where are you given this is the question?

[MainlyRaexx]

Let’s be honest we’re all here bcs of science class 💀

[glamorbyjoy]

I'm confused on how he got 3.37m for the first practice problem.

[stevenfordelon]

Im still confused idk why and pls read me
