Physics: Viewer's Request: Mechanics #2: Inclined Plane - Min. Force Required (1 of 5) Start Pushing

To donate:

We will find the minimum force, magnitude and direction, required to START PUSHING the block at rest UPWARDS.

Next video in this series can be seen at:

You, sir, are the reason why I am less stressed about work. Thank you so much for making your videos free online :D

[klustereman]

There is a mistake in ur chemical kinetics series, people have commented on that video i think u haven't noticed it, please check it

Hi sir, one small doubt how Acceleration becomes zero. is it because initially the body is at rest ?

[chompchomp]

What if we're given kg instead of N? What do we need to do? 😭

[arpitasahoo]

Great video Sir. You really explained the concept very well and now it's crystal clear to me but may I know how many markers you really do have? Idk why but those aligned markers along the board all of a sudden caught my attention during the query!

[exodia]

i think i have another opinion if you let me to explain this
the block will move downward under its gravity force mgsin30 which bigger than friction force = mg*mustatic*cos30
and then that friction coefficent will transform to mukin so friction force will be mg*mukin*cos30 so the minimal force to stop that from moving downward first will be =163.9N to overcome that gravity force mgsin30, so the force has to increase to move the block upwards so the friction will transform to be with gravity force and the force has to to increase to overcome this will be 410N, so we have two minimal forces first to hold down the block, second force to move up am i right? i wish u have space time to answer me

[genebelcherskeyboard]

i hope to be as knowlegable as you one day my king

I need to solve this . A 44 N block is thrust up a 30° inclined plane with an initial speed of 5m/sec. It travels a distance of 1.5 m before it comes to rest. The frictional force acting upon it would be? Can you please explain it?

[mohamedakasbi]

Hello, Calculating F I found 163.91 N, am i missing something?

[behzodfayziev]

Hi sir, thanks for sharing these videos. I would like to ask if the sign should be positive at 6:42 ?

Mr @UCiGxYawhEp4QyFcX0R60YdQ
I got an issue with this concept of inertial frames & states of constant velocity.
Is the it case, that for isolated matter, possessing motion in this universe is somehow regulated/restricted to quantized rate states, states where it can only pace space in equal amounts WRT a constant beat of time? These states would be similar to electron energy levels.
If so, then that may imply that space, time, acceleration, Force & Energy themselves are quantized. Help!

[lindsaywaterman]

Sir, this solution is incorrect. The force should be a pulling force up the plane at an angle of 16.7 degrees. The solution is very similar to your lecture #6 with the same angle, but instead of pushing down, one should be pushing up.

[azadkumar]

Dear sir please make an one video that how to find number of subgroup of Zn please please please please please please...

[jellyfrancis]

Let's say the force is given from an angle upward instead of downward which means the certain angle respect to tha side of the block ...then we get reduced normal force and by that the friction will reduce then we get even minimum amount of force as the answer to move the block 🤔💞

[aisyahmuar]

hi sir, can u make a video on how to find the height of the inclined plane?

[tsoojbaterdene]

Car accelerates 1m/s to 7m/s.How to find average velocity of first half of travelled distance .I hope you will answer my question.🙏🙏

[ghgjftythnhcfghdty]

I'd like to suggest a calculator that uses reverse polish notation instead of that conventional algebraic one. So much more elegant and efficient, you'll never look back. (HP35s is a good option)

Hi,

new subscriber on the channel.

I have a curious question which is off topic from this discussion...😊

how will I compute for the diameter and thickness of a 12lbs. flywheel?

would appreciate if you could cover this subject.

Thank you very much.

[jshah]

Could you tell me what grade this is for? I’m going into 6th but I’ll be taking 8th grade things in that grade? Do you assume I will be doing this in the fall, or the semester after that?

[elnursucayev]

Where we use kinematic frictional constant(μ=0, 25)?
