Ballistic Flight Equations

(4 days ago) So, according to Newton’s first law of motion, the horizontal velocity remains a constant and the distance x which the ball travels is given by the velocity times the expended time t: U = U0. x = U0 * t. In the vertical plane, weight is the only external force acting on the object.

Forces on a Baseball

(8 days ago) From Newton’s first law, we know that the moving ball will stay in motion in a straight line unless acted on by external forces. A force may be thought of as a push or pull in a specific direction; a force is a vector quantity. If the initial velocity and direction are known, and we can determine the magnitude and direction of all the forces

Flight Equations with Drag

A ball in flight has no engine to produce thrust, so the resulting flight is similar to the flight of shell from a cannon, or a bullet from a gun.This type of flight is called ballistic flight and assumes that weight is the only force acting on the ball. In reality, a baseball or a soccer ball in flight generates a moderate amount of aerodynamic drag and is not
