This actually very helpful, bro you are amazing and I came to this video to be disappointed but WOW please keep this content up and help more people in the future man, thanks again
Wow! As someone who is struggling with physics, I went ahead to relearn the prior chapters using your videos and you made it so easy to understand!! I'm so grateful for your video, thank you for your work! I'm finally able to asking a question without googling how to do it.
Before i watched this video i was totally hopeless l was even crying. Not because this concept in particular, but i just felt really overwhelmed because of my exams and when i struggled with this concept i just exploded and started crying. I watched many long videos and i didn't understand. But a 10 minutes video helped me and cheered me up. It may seem redecolus but i really needed to feel that at least something is easier than i thought ..
Brian Swarthout Thanks. :) I also left this comment on your website: Can you do videos on Kinematic Graphs? I'm learning that right now in AP MYB IB Physics at Suncoast High School. I just need clarification on interpreting the graph like at which point is the rest point, which point has the velocity 0, etc.
I have videos on motion graphs. You can see a listing of all my videos at my website, www.stepbystepscience.com Here is a link to the first one....ruclips.net/video/4J-mUek-zGw/видео.html
Step-by-Step Science please help me with this this is different it has speed before it drops what should I do then? A student measures the time required for a ball to roll across 0.5m of the lab table to be 0.4 second the height of the table is 1meter how far does it goes from the table? Please help me
I have a vide0 for this two dimensional motion problem. You would just have to figure out the initial velocity, distance / time or 0.5 m/0.4 seconds. ruclips.net/video/5oLvbJ71I2c/видео.html Does that help?
I really appreciate your explanation. I'm learning physics along with my daughter so that she does well. I just needed to play you video at 0.75 speed so that I can follow your speed of speech. Thank you.
I'm actually from the middle east and was looking for videos to help me with my studies, but yours exceeded my expectations. Have a nice day good sir. #LastNightBeforeTheExam
No thank you! You managed to help me understand a lesson I’ve struggled with for weeks, your videos are truLy amazing! Even years later you’ve helped so many people, keep it up! :)
I kid you not my teacher can't teach shit at all. He just answers your questions with questions. Makes everything so complex. You made it so easy, you actually explained everything, for the most part you showed me how to solve general questions. (Heres hoping the questions i get on quizzes/tests are just like these) THANKS FOR THE VIDEO
+Brian Swarthout Do you have a video on Vectors? As in lets say a Car Traveled East 50 M then South 75 M, find the Two types of displacements, two types of velocity. (Using the Tan -1 formula). Stuff like that?
Bro thanks so much this helped so much I have a test on this tomorrow and I was so nervous but watching this video make me feel more confident thanks so much
+Jenny J I tried to make a video for almost every possible basic situation. You can find a listing of all my videos by topic at my web site, www.stepbystepscience.com.
∆Y= 1/2 at² become t= √2∆Y/a Because we are solving for time, how did we come up t=√2∆Y/a in ∆Y=1/2 at² ??? Multiply both sides by 2 Therefore, 2(∆Y)= 2( 1/2 at²) 2∆Y= at² Divide both sides by "a" 2∆Y/a = at²/a 2∆Y/a= t² Square root both sides √t²= √2∆Y/a t= √2∆Y/a
Thanks for the comment and thanks for sharing. Where do you teach, I am currently in Berlin Germany. You can see a listing of all my videos at www.stepbystepscience.com
Can someone help me. What is the process for re arranging the equation to solve for time? I don’t understand the whole multiplying both sides and changing the formations of the variables.
Brian Swarthout i understand it finally although i can't derive the formula by myself if i just memorize the formula i can solve any problem with free fall, thanks for this tutorial sir I've watched all your 10 videos about free fall, I've answered them all before you gave the explanation to see if i get the right answer, and i did, now i am practicing on solving free fall with two or more object thrown from top, or thrown from bottom, this helps alot. thank you again. have a nice day.
I always get late in my class and such that physics is our first subject, I often find difficulties in catching up of what was being discussed, and the fact that my teacher's English sucks it even gets way harder to know what she's trying to say
I watch from those and try to go to momentum and torque !!!! I am in higher education. And I want to refresh my mind with basic physics to understand advanced physics ( classical mechanics). :))))
Thank you. 😇 I've got it. I'm G-12 getting the General Physics. But I shuffling my mind to all lesson that teachers gave every day. 😭😭😭 #TheFormulas 😭😭
*Does the moon have any effect onto the free fall of an object between the moon and the earth, or the free fall of an object from the left side of the earth while the moon is on the right side of the earth?* I watched some videos explaining free fall on earth without the gravity of the moon which has effects on the oceans to cause low and high tides on earth.
Anything that a regular person would drop onto the surface of Earth would not be effected by the moon's gravitational pull. The mass of the object would be too small and the distance would be too great.
The moon would have no noticeable effect on something free falling near Earth. The Earth's gravity would dwarf any effect of the moon's gravity. Things like tides are indeed caused from lunar gravity, but not really directly. Because the Earth is so large, there is a real difference between the parts of Earth closest to the moon and those parts farthest away, and this difference manifests itself through rising and lowering tides. This is very large scale stuff that doesn't have any effect on some regular object falling here on Earth.
It's one thing to discuss math, and word problems, but it's another to explain how the math works. Almost every discussion I see on this standard free fall equation fails to simply explain the purpose of the exponent (which can be eliminated by a much simpler reinstatement of the equation). By intuition, one thinks that if the gravitational rate of acceleration is 9.8m/s, then in 1 second an object will free fall 9.8m. But this is incorrect- It takes time for that acceleration rate to be achieved, and in fact, it takes literally half the time- which is why the division and the square. So if we restate this equation without the exponent, but doing it in a way that reflects that 'half'concept, we get this: Vf = Vo + (at/2) * t
The acceleration is not a constant it is a variable. Things dont always freefall at a constant rate of 9.81 m/s2 but everything falls in the state of constant acceleration.
This video is about free fall and when we talk about free fall we mean that the only force acting on the object is the force of gravity. And therefore it accelerates at a constant rate of 9.81 m/s2. Thank you.
@stepbystepscience The comment is for those that think gravity on earth is always and only 9.81 m/s2. It's not. It is an independent variable. Even gravimeters can measure different rates of acceleration in the same spot within different variable. So,.. freefall is not always precisely g=9.81 m/s2. It's just a chosen rate. Thanks for clarification.
Sir, I want to ask a question that Why sky diving (without parachute)is considered as Free fall, I get confused as there is air resistance in this... I am struggling a lot.... For it.. Please answer..
Free fall is when something falls (or is moving upwards) and only experiences the force of gravity. We ignore all other forces, even though they may actually be there. Sky diving may not be the best example of free fall, but if we ignore air friction....

life saver dude. Professors will teach the math parts like its science and just move on to the next slide. I appreciate this explanation.
You are very welcome, I find a good complete introduction is helpful when beginning a new topic.
When a 10 minute RUclips video taught me more than my teacher in two weeks
Wow, thanks for watching and commenting.
this hits too close to home
Hits too close to my online class right now
literally tho i have a test on free fall tomorrow and i had no idea what to do until now
Same bruh

I left class after 2 hours with no knowledge... I left here after 10 mins with knowledge.. ty
Fantastic, love to hear that!
Watching this bec I have a test tmmr and this taught me more than school
That's great, hope you did well!
k but can we talk about richard for a sec? girl..rude.
I know, sorry.
Someone tell Richard that that sort of behavior isn't very nice
This guy taught me in 10 mins more than what my teacher did in a month
Sorry about that, but thanks for the comment.
Thank you for the very clear and concise explanation!
You are welcome, glad it was helpful!
Thank so much sir. My whole unit is already conclude by 10 minutes. You had saved my credit >
You are very welcome, thank you very much for watching and commenting.
THANK YOU SO MUCH!!! , I had a hard time understanding it in class.
Great that you found the video helpful.
Thank you for your video !! This will help me start to understand free fall in my class ..! I HOPE you can can explain better than my teacher .. XP
∆Y= 1/2 at² become t= √2∆Y/a
Because we are solving for time, how did we come up t=√2∆Y/a in ∆Y=1/2 at² ???
Multiply both sides by 2
Therefore,
2(∆Y)= 2( 1/2 at²)
2∆Y= at²
Divide both sides by "a"
2∆Y/a = at²/a
2∆Y/a= t²
Square root both sides
√t²= √2∆Y/a
t= √2∆Y/a
You just saved my life. TBH, you teach physics better than my teacher.
Great, thanks for watching and commenting.
