In our recent experiment, we explored projectile motion on a 4-degree inclined plane using a rubber ball, a ruler as a launcher, and a string to measure displacement. Unlike traditional flat-ground projectiles, this setup required resolving velocity and acceleration vectors into components parallel and perpendicular to the slope.
Gravity, acting vertically downward, was split into two parts: one pulling the ball back along the incline and one pressing it against the surface. When released, the ball rolled and travelled up the incline until its forward velocity was canceled by gravity’s opposing component. We measured the maximum distance traveled along the incline using the string.
Although minor variations arose due to friction and launch inconsistencies, the results closely matched theoretical predictions. This experiment clearly demonstrated how vector components affect motion on inclined surfaces. Even a slight slope significantly alters projectile dynamics, making the abstract concept of vectors tangible and illustrating the interaction between gravity and angled planes.
