Theoretical simulations for the free fall trajectories of the spacecraft suggest that we can estimate the mass of the asteroid with the error of about 5∼7%% by LIDAR.
By contrast, a freely-falling trajectory is a freely falling trajectory in any coordinate system; it is only the decomposition of it into its inertial and gravitational parts that will be different in different coordinate systems.
The movie largely follows the same rise-and-fall trajectory as a lot of music biopics, which doesn't make it any less touching.
But then it refuses to follow the usual rise-and-fall trajectory — it just keeps rising, to movie mogul, billionaire and most powerful man in show business.
Directed and edited by Ms. Schemel's friend P. David Ebersole, "Hit So Hard" largely follows the same rise-and-fall trajectory as a lot of music biopics, though its openly sympathetic approach feels rooted in a real friendship rather than in sensationalism or industry boosterism.
When they spot a red, blue or green flake originating from one of the milk bottle tops, they pass this information to a computer which calculates the falling trajectory of this flake and the time it will take to reach a line of compressed air nozzles.
It's actually nothing but the falling trajectory, shaped in the air, and driven just by gravity.
During this free-fall trajectory, the resultant of all forces acting on the aircraft other than gravity is nulled.
During this free-fall trajectory, the resultant of all forces acting on the aircraft other than gravity is zeroed.
