Horizontal Motion
Think of throwing a ball sideways - once it leaves your hand, nothing pushes it left or right anymore. That's exactly how horizontal motion works in projectiles.
Since there are no horizontal forces acting on a projectile after launch, it travels at a constant horizontal velocity. This means it covers the same horizontal distance every second throughout its entire flight.
The range (how far it travels horizontally) is calculated using the simple formula d = vt. Here, d is the horizontal distance in metres, v is the horizontal speed in m/s, and t is the time in seconds.
Quick Tip: On a velocity-time graph, horizontal motion appears as a straight horizontal line because the velocity never changes!
