Certainly! Here are the definitions of the terms you've requested:

a. Projectile Motion

Projectile motion refers to the motion of an object that is launched into the air and is subject to only the forces of gravity and air resistance (if considered). It can be described as a two-dimensional motion with horizontal and vertical components. The object follows a curved path called a trajectory, usually in the shape of a parabola, under the influence of gravitational acceleration. The key characteristics of projectile motion include uniform horizontal motion and uniformly accelerated vertical motion.

b. Trajectory

The trajectory of a projectile is the path that it follows as it moves through space. This path is determined by the initial velocity, launch angle, and the effects of gravity. In the absence of air resistance, the trajectory of a projectile will be a parabola. The trajectory can be analyzed in terms of displacement in the horizontal and vertical directions as a function of time.

c. Range

The range of a projectile is the horizontal distance traveled by the projectile from its launch point to the point where it returns to the same vertical level (e.g., the ground). It is influenced by the launch velocity and angle, as well as the initial height from which the projectile is launched. The range can be maximized by launching the projectile at a specific angle (usually 45 degrees) when air resistance is negligible.

d. Resolved Velocity

Resolved velocity refers to the decomposition of a vector quantity, such as velocity, into its component parts along specified directions, typically horizontal and vertical components. In the context of projectile motion, the resolved velocity is typically expressed as two components: the horizontal component (Vx) and the vertical component (Vy). This allows for a more straightforward analysis of the motion in each direction separately, especially when calculating distance, time of flight, or resulting trajectories.
