The zenith angle is generally easier to work with. a slope directly, you may sometimes have, 9. How to find horizontal distance in projectile motion? Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Open both eyes to sight the object and read the scale. As with equation 11.5, this equation still gives a highly accurate estimate for the vertical distance between two stations if h is simply assumed to be zero; for distances of up to 20 km, the resulting error in the value of "h will be less than one millionth of the measured slope distance. The slope percent equation can be rearranged to provide the equation for the horizontal distance.
