Centripetal Force & Acceleration Physics Lesson Part 1 Dynamics

YOU GUYS NEED TO MAKE MORE VIDEOS LIKE THIS!!!.

@Billabong024 Thanks. We are planning to make some more in June. Glad to help.

A gravitational force field has two sub fields; one excursive which i've named the X-gravity factor that acts as a repulsive force against other worlds and gravity which coalesces and unifies matter towards a concentric point from whence it radiates. Both fields accrue pressure starting at the plane of the exosphere but in opposite directions In my theory both of these fields can be interpreted as having a centripetal force and the other a centrifugal, however; their forces revert with direction

How did you isolate V? I got a totally different answer.

@Usurperrhcp Yeah it took me a few minutes after I posted this question to find the answer. But thanks anyways!

you should make some lessons on electronics and photonics!!

@123codfan Thanks for the suggestion. We may try sometime to do this.

Why do you say when the tire turns,FF will be generated to the middle of the circle??

@phuajiawei In order for the car to turn, a force is required toward the middle of the circle. When the car wheels turn, they push against the road and the road reacts by pushing back. This force is the friction of the road and it is toward the middle of the circle. When the wheels are NOT turned, the car has no sideways force and does not turn. So turning the car wheel makes the friction force that can turn the car around the circle. I hope this helps.

@PhysicsEH It doesn't help....IT HELPS ALOT!Thanks a ton ^.^!

@phuajiawei Thanks for the great comment.

@SaadFCB The important point is that tires create friction when you turn the wheel. This friction is toward the centre as you turn. It's also importnat to understand that any object moving in a circle has to have a force toward the center of that circle and the friction force therefor is the one that is providing the force to keep the car going in a circle. If the friction is too little than the car can not go in that circle but a larger one will work so the circle gets bigger. I hope this helps

I have a question regarding the free body diagram. Wouldn't the force downwards actually be weight rather than gravity?

Weight, Fg, gravity, mg: they all represent the "downward" pull from the earth so any label is usually accepted

i wish i took honors physical science instead. im sooo a chemistry person..

hehehehe I love how I understand all this. Freshman taking physics 'cause im a boss like that :)

this is just... amazing. so clear. and covers everything. if only i had found these videos sooner lol. thank you so much!

Clear, easy to follow and short. Yours are the ideal physics lessons! Thanks for sharing with us! :)

physics...EH?

looks like a "5" is waiting for me in physics C..........:P

Thank you... im struggling with Physics so much right now and I came across this :)

pls reply to this one............over here if friction is created,then it should oppose some force......because it is a reaction force....i understood the rest,just i cant get how is the friction created here?

The car moves forward and the wheels are turned. Because the cars inertia wants it to keep moving forward in a straight line but the tires which are a little sideways and want to turn, the tires push on the road and the reaction to that is the road pushes back on the tires (friction). Imagine if you could turn the tires to 90 degrees while the car is going forward, the tires would scrape against the road and the car would skid. Its the same force when turned a little only its a bit sideways.

centrifugal force is FAKE!!!!

he's from Canadialand!

Thank you very much for the video. I am staying physics all by myself and I have some problem to understand centripetal force. If the car is moving shouldn't it be some applied force?

got it.that means that the weight of the tires(mg) and the normal reaction cancel each other. then the tires are a bit sideways while the car has inertia of motion along the tangent....which is away from the circular path...so its reaction(friction) is towards the center of the circle.....thanks a lot. i am in 11th grade..this helped a lot.

and of course the friction is more than the action force....thats why it tries to move the car towards the center...and that force acts as the centripetal force

I have an easy time getting intuition for what things are but my laziness prevents me from profound understanding, this video though helped me get an A in my first test of the year! I have a question that is really off topic, hopefully someone knowledgeable could answer it: I'm wondering if math and physics teachers always understand completely what they're talking about or if they mostly accept some things? I mean, will a teacher memorise formulas or just say hey, that's obvious!?

....... comment continues (sorry): For instance when you say that we need to accept that the acceleration goes to the center, does that mean that it's better for students that are short on time and have upcoming tests and other subjects to also worry about, or does a person as intelligent as you (come on, you teach physics) also accept it or can you comprehend why it is that way just like an average joe really understands why 1+1=2?

graduated from EH last year, still using these videos

Is friction always towards the centre when an object is moving in a circular motion?

Now if only my teacher were this helpful. Or rather, the problems in my class are a tad bit more difficult. I just need to try harder I guess.

why is force of friction in the same direction as the acceleration?

waait a second. doesn't it make more sense that an object traveling in a circle has centrifugal force?

my reaction exactly!

Thank you very much. It really helped :)

Thank you so much. I'm in college and I'm watching your videos! Very thankful. :)

You're just swell :)

He's just saying the car has a positive acceleration.

thats not the formula for Ffriction tho its for Fc

if there is friction at all, what will happen? the car keep going straight line?

This helped me so much, thanks

fuck physics

Thank you so much! It really helps that you explain each step you're doing. Sometimes in class it's hard to copy down notes while trying to understand as well so this is really helpful. Keep up the great work! :)

A "toy" car that weighs 100 kg? :P

I'm confused how did he got 10?

Your are cute

Have my finals in 1 hour and 50 minutes. Thank you for your videos. I honestly don't know if i'd have a chance of passing if not for your videos! But really, I hope you all have a great day, I am gonna study for another hour and then take my test!
