PPT-Vertical Motion under Gravity

Theories of motion Aristotle was a Greek philosopher who lived in the 4 th century BC Aristotle explained the behaviour of a falling body by saying that its speed depended on how much earth element it contained . A projectile is an object upon which the only force acting is gravity. .. An . object dropped from rest is a projectile (provided that the influence of air resistance is negligible). .  . An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). . :. Place on Your Desk:. *Calculator & Protractor. 1) .

Gravity and Motion. 2. Introduction. Gravity. gives the Universe its structure. It is a universal force that causes all objects to pull on all other objects everywhere. Problems will be solvable using the equations of uniform acceleration. . .  . Projectile motion. This section is devoted to understanding the motion of projectiles. A projectile is an object upon which the only force acting is gravity.
