AI Thread Summary
Projectile motion can be converted into a parabolic equation using specific formulas that account for velocity and direction. For programming a motion planner in a game, the range formula helps determine the x value, while the total time of flight can be calculated using a similar approach. The equation for vertical motion under constant acceleration is y(t) = (1/2) a t^2 + v(0) t + x(0). In cases of variable acceleration, numerical integration of the velocity function is recommended. These equations provide a solid foundation for simulating parabolic motion in game development.

I was wondering if it is possible to convert a projectile motion(velocity, direction, etc) into a (parabolic) equation.
I am programming a motion planner to use in a simple 'game' that I am making.
A formula would be appreciated.
I was thinking something like http://img99.imageshack.us/img99/187/eq220d30dcno9.png
To get the x value I am using the range formula

I am then using a similar formula to calculate the total time of flight.
Then I am dividing the range by the total time of flight.

hello?
 
If the acceleration is constant,
y(t) = \frac12 a t^2 + v(0) t + x(0),
otherwise you should take something like
y(t) = \int v(t) dt = \iint a(t) dt dt
and do a numerical integration.
 
Thanks.
 
Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Thread 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
