Projectile Motion analytical solutions

Click For Summary
SUMMARY

The discussion focuses on finding analytical solutions for projectile motion, emphasizing the importance of the environment in which the projectile travels. The initial equation provided, velocity = initial velocity - acceleration * time, is accurate for constant gravitational fields. To derive more complex solutions, one must start with the equation F = dp/dt, which incorporates the vector sum of all forces acting on the projectile. However, analytical solutions may not always be feasible, necessitating numerical methods in cases involving drag or varying air densities.

Hi, I'm trying to find the analytical solutions to projectile motion, and not just the approximations.I know the Euler approximation for velocity is the inital velocity - acceleration*time, but what is the more accurate analytical solution for velocity.Thank you.

That depends on the environment the projectile travels through. The equation you have is perfectly analytical and exact for a projectile that travels only in a constant gravitational field (within the regime of classical mechanics).

To find a solution for a certain environment you will need to start with [itex]F= dp/dt[/itex]. On the left side you have the vector sum of all forces acting upon the projectile. Then all you have to do is solve the differential equation. Unfortunately that is not always possible analytically at which point we'll have to do it numerically.

Yes no drag, changing air densities or anything.
Ok so this is the most accurate equation. I will use it then.
Thanks.
