- It is the horizontal distance traveled by a projectile with a uniform velocity in the time of flight between the points of projection and impact.
- It is denoted by R.
The Trajectory of an Object Fired Horizontally
- Let us consider the origin O of a coordinate system as the point of projection, the vertical line OY as the y-axis and the horizontal line OX as the x-axis.
- Suppose an object is fired from the point of projection O at a height h above the ground with an initial velocity u horizontally. The point O is like the top of a tower of height h.
