Newton’s Laws of Motion
Newton’s Third Law: Action & Reaction Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. His third law states that for every action (force) in nature there is an equal and …

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
(4 days ago) 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
