How to Calculate Kinetic Energy

[@abbeyschubert1531]

See I didn’t do a week of online school, I come back 2 days before unit test, watch this video and his potential energy video and IM ALL CAUGHT UP, what a G.O.A.T this man is a life saver, why couldn’t u be my teacher?!?!?

Sir, I would be very delighted if you could keep publishing videos like this on Physics and Math. As an engineering student who learns better by videoeos, I have not seen a person explain something quite as good as you. Thank you for the video. I hope you will be back with more.

How did you get the 1,134,375 like how did you solve? Cause you just said lets calculate it but i don't know what to do like times or divide? Pls help

[@samarchuleta5993]

He squared 55 and got 3,025. He then multiplied it by 750 and divided that total by 2. It's been about a month so you've probably already figured this out but just in case you haven't.

Wow this is the only video I’ve watched that’s actually taught me how to do this

[@vou8119]

how u get that two at 6:17 ?

[@bridgernicholson5048]

dividing by 2 is the same as multiplying the same thing by 1/2 for example 10/2=5 and 10*.5=5. so he just divides by 2 instead of multiplying by 1/2 because it is the same.

[@seeyahatxea6279]

how did you get the answer 5.1 what did you do in the divide ........ i didn't get that part????

[@hidesato919]

Thank you so much for the tutorial. I have my second quiz tomorrow for my physics class and we will be going over kinetic energy. Sadly, my professor doesn't really go over the step by steps for most formulas in class. You are a lifesaver sir, thank you again.

So, if we could measure the REAL kinetic energy of a 1 kilo block of metal that sits still on a table, minus rotation of earth, minus revolving around the sun, minus revolving around center of the galaxy, we would know how fast were moving away from the center of the universe?

[@rosebox2578]

How you end up with 1,134,375 j

[@renforest]

so using the formula m multiply v square divided by 2: 750 multiply 55 square (you press the square feet symbol on your calculator) which should equal 2'268750 and then divide it by two. Which your final should be 1,134,375 J hope this helps!

[@johnjoseph1687]

Thanks... you explained better than he did. Smh.

[@nexus1g]

In mathematical "grammar", you calculate the power first (that is the square of the velocity in this case) then work left to right to solve.

[@elelyon555]

Yes she did! I thought .55 squared is .55 X 2 = 1.1 using a regular calculator and not those calculators w/squared functions which I don't have. The teacher should point out in the video beforehand to clarify this!

If we have Mass is rest mass in given question. so here we will put direct in formula for kinetic energy KE=1/2 MV^2 ?????????? Or we need to first calculate Realistic mass valve through [M=M(rest mass)+ r] formula , after that will we calculate Kinetic energy???

How did you get the 1,134,375kg?

He divided 750 into 2 so 750 ÷ 2 = 375 and multiplied 55 twice so 55 x 55 = 3,025 and multiplied the 375 and 3,025 so we get 375 x 3,025 = 1,134,375

[@gregsancientegyptfactsandg7711]

do you always have to convert your values into Kg and m/s to find kinetic energy? For example, say I'm given an object with mass 500 grams, is it correct to say that I have to convert 500g= 0.5 kilograms before plugging it in?
