Esophageal cancer describes the disease where cells that line the esophagus change or mutate and become malignant. These cells grow out of control and form a mass or tumor. There are two main types of esophageal cancer:
Trajectory. A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbitâthe path of a planet, an asteroid or a comet as it travels around a central mass.
Parabolic water trajectory. Initial velocity of parabolic throwing. Components of initial velocity of parabolic throwing. Projectile motion is a form of motion in which an object or particle (in either case referred to as a projectile) is thrown near the Earth's surface, and it moves along a curved path under the action of gravity only.
