What Is Relative Velocity? | Physics in Motion

We travel onboard a boat to investigate the topic of relative velocity and to show how all motion is relative.

I've been stuck on this topic for 5 days. I don't know why but it didn't make much sense when I saw other videos. But I think I can move on now. Thank you so very much!! You are the boat that saved my life...
Sorry that was a little dramatic...Maybe I paid too much attention to that boat!

I had watched so many videos on this topic but not a single video could explain the concept properly. But this video is the best one available on YouTube. Thanks Adrian!!

Beautifully explained, I understood very quickly. This method of teaching is very effective.

[craigconway-no]

Thank you for explaining this simply. I get it now

[rickg]

when you started walking perpendicular to the boats movement thats when everything came clear, thank you very well explained

[joannetheoo]

This video explained the part in our p6 module
where I've been stuck for quite some days now >.<
thank youuuu!!

Take away absolute and relative rest/motion and you have the experimentally correct:
1) the observer is always at rest 2) all other systems is always in motion.

nice explanation with detail examples and understandable voice too

[hannahsaseun]

good job... some good explanations up there

[Lolo-yoyo]

Thank you for doing what my science teacher couldn’t ❤❤

To be technical, you are not moving northeast in your 2D example, you are moving at an angle of arctan(2/5) to the north of east. You would only be moving northeast if the angle were 45 degrees, which it is not. Students often confuse (sort of NorthEast) with actual NorthEast.

I enjoy the lesson than any other lessons because it teaches dip

That boat IS NOT going 5.39 m/s NE. The arctan of 2/5 is about 21.8 degrees. So the boat is moving at a velocity of 5.39 m/s at 21.8 degrees N of E relative to an observer on the dock.

But i guess you were sitting on the boat or standing still n how come your speed is different than the boats speed?

[karthikp]

I am still confused which arrow placed first, Why?

[jeemotivation]

I am in class 12 and this topic helps me in ray optics

Om namah shivay

A very good lesson for physics students thanks brother

[mohamedluqman]

Nice bro I got more useful information

Your first statement about movement, was True.
The boat was moving, behind you, as you stood on the stationary shore.
Your 2nd Statement was Not True.
You were Standing Still While on the Moving Boat. Whereas the shore was not moving at all. Still. Not moving at all. Due to the boat's movement it gave the illusion that the shore was moving, thatm if you have no clue about reality. That was rather deceiving, and your lie, a very poor attempt at such non-sense being told as true.
You should be ashamed of yourself attempting to deceive children as you knowingly did.
