Rollercoasters are exhilarating and fun
What a lot of people dont see is all the physics thats goes into bulding the coaster itself
The potential energy from the height is converted into to kinetic energy from the fall and that kinetic energy is enough to up again and gather gravitational potential energy again.
My favourite rollercoaster is definitely dragon fire because it has so many loops and twists with minimum amount of gravitational potential energy. The calculations were very good as the ride was awesome and fantastic!!!
I reccomend it to anyone who dooesnt like a lot of high drops on roller coasters like me.

Projectile motion basic (confusiiinngg!!)
Since our brain learns better through interaction or flashing thats why we did a discovery lab in class to fugure out how the 2 dimensional vector components work in real life
The horizontal or x component will have zero accelearion and constant velocity
the vertical or y component will have a initial velocity of 0 m/s and will have an acceleration of 9.8 m/s^2
so for the x component the formula would be Dx=VxTx
and the formula for the y component would usually be Dy=V1yTy+1/2at^2
if enough information is not given for one of the components then usually there is enough information for the other component and the variable found could be pluggged in the first component formula.
This way u can find out whatever u want with projectile motions.
Hurray!!!
im still not as fast at these problems yet even though I explained fine ont his blog
I ll get better
no worries

Vectors are awesome!!!
Okay so this blog is about how to add vector components
In class, our teacher gave us a brilliant way or example of how we can break down vectors and add them!!
Are you ready *drum roll*
HE TOLD US TO BE LIKE NEO IN THE MOVIE MATRIX
confused?
it means that just like neo saw everything in binary code, we should break every component down into "x" and "y" components
so if there was a a diagonal component we should:
- find the x and y vector components
- use those to find the angle of the diagonal component
- and if there is a problem that needs to be solved then make a table and plug in the x and y values for each diagonal component and then add, subtract etc
- once you have the final x and y components then use Pythagorean theorem and tangent to find the length and angle of the final diagonal component.
Remember to have it as ___(S.I unit) [N/S___(degree)E/W]
OH one last thing
dont forget to set your positive axis
I will most likely use north and west but depending on the situation, those should be altered.
