WebDec 22, 2024 · On the Earth’s surface, the constant acceleration a is equal to g = 9.8 m/s 2, and an object undergoing projectile motion is in free fall with this as the only source of acceleration. In most cases, it will take the path of a parabola, so the motion will have both a horizontal and vertical component. WebWhen a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object. There are three key ingredients to work - force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.
