Horizontal motion refers to the movement of an object along a straight path parallel to the horizontal axis, often analyzed as part of projectile motion where it is independent of vertical motion. It assumes constant velocity when air resistance is negligible, meaning acceleration is zero and the only force acting is gravity in the vertical direction.

The horizontal axis, often referred to as the x-axis in a coordinate system, represents the independent variable or the basis upon which values are plotted. It is crucial in data visualization, allowing for the clear representation and comparison of data points across a defined spectrum or time series.

Projectile motion refers to the motion of an object thrown or projected into the air, subject only to the acceleration of gravity. It is characterized by a parabolic trajectory, where horizontal and vertical motions are independent of each other except for the time of flight.

constant velocity

Air resistance, also known as drag, is a force that opposes the motion of an object through the air, increasing with the object's speed and surface area. It plays a significant role in determining the terminal velocity of falling objects and affects the performance and efficiency of vehicles and projectiles.
