Please sir, can you explain the second average speed formula. The first one was Xf - Xo/t which made sense but this second one: S = Xf + Xo/2 is really confusing sir.

[@7877-x4w]

Can you please link me a video or the video I tried to go ahead on this problem and failed horribly I just need more examples and example problems with solutions so i can maybe work through them on my own to understand it better because I’m horrible at kinematics and I’ve already made it to 2d motion please

Thank you. I am an online college student and I always come to your channel when I'm struggling with subjects. You always make them so much easier to understand and the way you break things down so simply really helps me feel confident with the material.

[@danielalexanderyt3232]

For self-reference... Scalars are just the items themselves (magnitude) with no direction or anything (speed, distance) and Vectors are the items with the direction (velocity, displacement). Velocity is the speed with the direction and is calculated with Displacement/Time while Speed is just the rate at which something moves (no attention to direction, hence why it is not a vector) and is calculated with Distance/Time. Scalars like speed and distance have no direction, so they are always positive, and vectors like velocity and displacement do have directions, so they can be positive and negative. You calculate distance by adding up the amounts traveled as their absolute value, regardless of direction. You calculate displacement by comparing the final position with the initial position (no attention to distance but instead to final distance from initial distance) (ex. Sal moves 10 in east, 11 west: The displacement would be -1 because the initial position is assumed to be 0 and after Sal went 10 places east, he returned 11 west, and so ended up 1 place more west than where he started, which was 0, hence since it was going to the left side, the displacement is -1. Instantaneous (speed) vs average (speed) is that instantaneous is calculated as an absolute value and tells you the speed at an instant in time, while the average speed tells the average over an interval. Avg. velocity is displacement (final position minus initial position)/time, while Inst. velocity is the change in displacement (final position minus initial position)/over the change in time. Displacement along the x-axis and y-axis are essentially the same, the only difference is that it is the final position minus initial position in the x and y axis accordingly. Average velocity is (displacement) change in position (X final- X initial; displacement;)/time, while average acceleration is the change in velocity (v final- v initial)/time.

Anyone noticed the inconsistency, or is it just me??? In the beginning of the video -4-(+13) =+9 and here at the end -90-(+50) =-140 This is confusing when I try to find Xfinal - Xinitial

[@tinewordsmith126]

Same here! I'm. In algebra, -4-(+13) is -4-13. It should equal -17, not +9 (just like what he did on the last example -90-(+50) is -90-50)

[@yeahyeah9639]

I have a question. 8:04 to calcululate the initial postion I would assume it would be 0 right? And then the final postion I would do 13-4 =9 and then using the formula 9-0=9 . Is this the correct way? Please help me I’m a 9th grader and a little scared about physics 😢

Then why is the displacement in the first example -50 instead of -250? If the particle started at the origin and traveled 100m east, then turned back around and traveled 150 west. It should be final-initial, which would be -150-100?

[@paysonkeown2960]

The origin is the initial, he moves 100 E and 150 W, so 0+100-150=50

[@tinewordsmith126]

​@@paysonkeown2960if that is the case, then the last example should have been -40/5hrs, because 0+50-90=-40, not -140

[@paysonkeown2960]

@@tinewordsmith126 the last example is different. It’s saying that in 5 hours you go from somewhere to the east to somewhere in the west. Final-initial for displacement gets us -90-50=-140

Im confused with the problem. I thought avg velocity is displacement/time but why was it 140 miles instead of -40?

[@thephysicsuniverse]

31:09 Because we’re going from +50 to -90. That’s a change of (-90)-50=-140. If it went from -50 to -90, then the displacement would be (-90)-(-50)=-40.

You could also go into horizontally launched projectiles. Let's say bob kicks a ball 10m/s on a 100m cliff 45 degrees. How far does it go? So the velocity in the y would be sin(45)*10m/s and the velocity in the x would be cos(45)*10m/s y = 8.509m/s x = 5.253m/s Now that we have the velocity in the y (8.509m/s) We will make a height vs time function. The double antiderivative of -9.8m/s is -4.9x^2 so -4.9x^2 + 8.5x + 100 = 0 now we use the quadratic formula(-b±√(b²-4ac))/(2a) and get a result of: 5.4s It will take 5.6 seconds to reach the bottom. Now we need to multiply this with the velocity in the x (5.253m/s) and we get our distance D = 28.665M (5.6 * cos(45)*10m/s)
