Projectile motion is an important concept in physics and a very crucial topic for MDCAT students. It is the motion of an object that is projected into the air and moves under the influence of gravity, following a curved path known as a parabolic trajectory. This motion is two-dimensional, with horizontal and vertical components acting independently. Understanding the principles of projectile motion is imperative to solve questions relating to trajectories, velocity, and time in the MDCAT Quiz.
Understanding the Components of Projectile Motion
Projectile motion can be separated into two independent components: horizontal and vertical. The horizontal motion is at a constant velocity because there are no forces acting in that direction externally (ignoring air resistance). On the other hand, the vertical motion is under the influence of gravity, where the object accelerates downward at a rate of

. The motion equations for both components are:

MDCAT Quiz: Projectile Motion Questions
The MDCAT Quiz often includes problems requiring students to analyze projectile motion. These questions may involve calculating the maximum height of a projectile, the total time it spends in the air, or the horizontal range it covers. For instance, a typical question might ask students to determine the range of a ball launched at a specific angle with a given initial velocity. To solve such problems, students must decompose the initial velocity into horizontal and vertical components using trigonometric functions and apply the equations of motion systematically. Practicing these problems improves understanding and prepares students for high-scoring performance in the MDCAT physics section.
