Projectile motion

See ppl

I am going to start a new thread on PROJECTILE MOTION . Here I am trying to make the theory part really simple .

All those who visit this , can discuss problems doubts etc etc.

I have various question banks?. And I am going to post different questions based on Projectile motion?..

You can also post ur own question over here.

All those who already finished this chapter

U can have a look at my explanation and correct me if I am wrong?

U can clarify doubts based on this topic here itself

And ofcourse u can post ur own question if u want to.

All those who did not finish the chapter yet

U can make use of this discussion?..!!!

Basically LET ALL OF US MAKE THIS DISCUSSION ABOUT PROJECTILE MOTION REALLY BIG??!!!

ALL THE EXPERTS

Please try to help us by clarifying doubts and putting up numerical problems and also by correcting us?.!!!

I will try my best to make the material really comprehensive and interesting and helpful..

PLEASE PARTCIPATE IN THE DISCUSSION

THANK U?????.!!!!

I am going to start with the basics first.............!!!

First I want to start with equations for uniformly accelerated motion??

You are already quite familiar with the equations of motion when the motion is along a straight line and the acceleration is constant.

The equations are as follows:

NOW WE CAN DERIVE THESE EQUATIONS USING GRAPHICAL METHOD

(please let me know if u can't see the image...)(i'll upload it separately which u can download and view)

When time =0 the initial velocity = u.

Acceleration (a) is constant therefore the velocity increases at a constant rate.

Therefore the time velocity graph of the object is an incline straight line.

When the time = t the velocity = v.

U should notice that on the line AB, B is the point corresponding to the time t.

Therefore the coordinates of this point B is (t,v)

Post 3 will demonstrate the derivation.

i will demonstrate the derivation soon.............!!!

hey sorry to ...tell this but as we are grown up it wud be better ..if we do it with integration ..actually we derived ur base equation using the equation of motion.he he .:P but anyways ...i believe u know the integration method to derive it...n i appreciate ur interest in helpin gothers...go ahead...

sinjan.j

yes i would be doing the integration method after i finish with this.
i want to start with the basics.
thanx for ur suggestion.

look a the pic and visualize the following

let us say that from 0 sec to t sec the displacement is s.
we also know that in a time velocity graph, the area enclosed between the graph and the x(time) axis gives the net displacement.

this is how we derive the equation....!!!

post 5

thats all about graphical method....!!!

sinjan.j

next i will be discussing the derivation through integral method.....!!!!

post 6

sinjan.j

tommorrow i will be posting the other two integration method derivation....

and then i will slowly proceed onto the projectile motion..

lalsa

good effort ....sanjan ...

I will also try to post something tomorrow
