Projectile Motion

So for the past two days, physics class was composed of determining projectile motion

On the first day, we all attempted an experiment with a marble and a ramp on a table. The marble was rolled off the ramp, and the elapsed time was taken from the point the marble left the table to the point it hit the ground.

On the second day, we just learned the conceptual stuff behind projectile motion.

So basically, when an object it released at speed, the gravity is taken into account while the object slowly drops.
However, there are two points in which to take into consideration. The first one being the movement on the x-axis (horizontal movement), and the second one being the movement on the y-axis (vertical movement). The horizontal movement is always at a constant velocity (the velocity at which the object was released), and the vertical movement requires the addition of gravity (9.81 m/s²). Usually, the vertical component begins with a V1 of 0, because it is dropped onto the ground, therefore, there is no initial velocity. Also, the height of the object is usually the distance the y component travels before it hits the ground.

Furthermore, the elapsed time of the x component should be equivalent to the time for the y component. Knowing these facts, many different pieces of information can be obtained using the big 5 equations.

That is a brief summary of projectile motion :)
