PROJECTILE MOTION

Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown near the earth's surface, and it moves along a curved path under the action of gravity only. 

This time i won't explain how to measure any quantity in projectile motion cases. If you need it just see my slide in "Materi Ajar Kelas XI". 

Yup grade XI, once upon a time grade XI my beloved students in Narada School try to show me the projectile motion using Water Rocket. So, Ya directly we went down to the basket ball field to make it.

Actually i've prepared the launcher already ( Thanks to Mr. Alex ), i just want to see how they launch their rocket based on their experiences in Junior high.

Well..i give a big applause for them who have tried so hard to launch their rocket. 

Can you see, why does Hanafi use a protractor??Yeah, she try to launch the rocket with an elevation angles. So you guys want to see what will happen with the rocket if you change the angle with 30, 45 or 60 degree right? well done guys, the result must be 45 degrees as the farthermost.

And here we are "Calvin the Great"..... His effort in this experiment so crazy...Push the pump,Connecting the hose when it broken off, until...his cloth got wrapped..wet..wet..wet.. 

here another picture for their activities :

"Budiman the Initiator" and his group.

Vinny looks so happy rite? hihi... 

Like i said before, look...our hose is brake off...

Ok, That is all our experience to flying the Rocket ...
