In this video we are going to learn about

inertial and accelerated frames of references First one. Inertial frames of reference. Frames of references where Newton’s Laws are applicable

is called as Inertial frames of reference The simplest example being Earth

All the Newton’s laws are applicable when we consider motion with respect to Earth

So Earth becomes our simplest IFR Frame of reference atrest or going at constant

velocity with respect to inertial frame of reference is also called as IFR

So any object which is at rest or it is going with a constant velocity with

respect to Earth then such a frame of reference will also be called as inertial frame of

reference For example a bus moving with constant velocity

with respect to the Earth then it will be called as inertial frame of reference

Next one accelerated frames of reference Frame of reference accelerating With respect

to inertial frame of reference is called accelerated frame of reference

For example a bus accelerating or decelerating with respect to Earth will be termed as AFR

Also a bus accelerating with respect to another bus which is moving with a constant velocity

is also termed as AFR Now let us try a few examples to understand

whether the given system is AFR or IFR One question you have to ask is

Whether Newton’s laws are valid or not The first one train speeding at hundred kilometers

per hour The train is speeding at hundred kilometers

per hour means it is moving at constant speed so it is inertial frame of reference. The laws are valid Next one merry go round anyone who has seen

a merry-go-round knows that it turns at a constant speed but at each and every point

the direction keeps on changing hence it is AFR Next one. A car taking a turn a car taking a turn A car taking a turn a car taking a turn has changes in velocity as well as acceleration

hence it’s AFR Sudden brake in a car

A car moving with constant speed and suddenly stopping has decelerated with respect to Earth

hence it is also AFR Last one hovering balloon a balloon hovering

over the given point is considered to be at rest with respect to

Earth hence it is IFR So now you get the general idea about AFR

or IFR We are going to apply this concept in problems

involving objects moving up and down in an elevator pendulum suspended in a moving or

accelerating elevator Or cases like this where a bag is lying on a

top of a speeding car and to find out whether it will slide off or not

Well done! Thanks for the video!

goood

Please make video on vectors

thanks you so much.

Why you are talking AFR when in the title you've talked about Non IFR

if we consider a bus travelling at constant velocity in India and similarly one in England does that mean they are in different inertial frame of reference .(acceleration is different for each bus)

In fact since rotation is the universal norm is an inertial frame of reference possible ?

Then since angular momentum is conserved what was the source of the rotation.

I am an duff einsteinian.

something wrong somewhere !

Sir agr body k mass zyada ho aor F kum ho to is m acceleration produced nhi ho ga to kya is pr second law apply kry ga please reply

For a train speeding at 100km/h the wording makes it sound like the train has acceleration. I think you meant to say the train has a speed of 100km/h not speeding

How Newton's laws can't be applied in AFR

Nice

Well explained. Thumbs up!

Thank you madam

I didnt understand mam cant u in hindi

Why is inertial frame of reference called INERTIAL?
