Projectile Motion!

To calculate a projectile motion problem, initial velocity, final velocity, accerleration, time, and distance are included, but the mass of the object is excluded. The key to solve the projectile motion problems is to break in two components, the horizontal and vertical component.

As we know that the gravitational acceleration is 9.8m/s². The acceleration in the y-component is always 9.8. If the speed of the obeject would be constant in the x-component. As we know that the speed acting on the object is just begin, the initial velocity/ the highest point of the object in y-component would be 0.

There are 4 types of projectile motion, the first type would be an object from the top and a force acting on the horizontal component. This kind of projectile motion can be solved by determining the time. In this case, the initial velocity of y-component is always zero and the velocity in x-component is always constant.

※The first type of projectile motion

The second type of the proejectile motion would be an object that has a velocity against the gravity. In the highest point of the whole projectile system, the velocity would become zero and the acceleration is determined as negative 9.8.

The third type of projectile motion also would be an object that have a velocity that against the gravity. But in this case, the displacement in y-component is not zero any more, there would an positive number in the y-component.

The last type of projectile motion is an object that habe a velocity that against the gravity and end with a negative displacement in the y-component.
