An "incline" refers to a surface that is slanted or tilted, rather than being flat. This can be seen in hills, ramps, or even the slope of a roof. Inclines are important in various fields, such as construction and transportation, as they help facilitate movement. For example, a wheelchair ramp is an incline that allows people to access buildings more easily. In physics, an incline is often studied to understand how gravity affects objects on slopes. When an object, like a ball, rolls down an incline, it accelerates due to the pull of gravity. This concept is crucial in understanding motion and energy, making inclines a fundamental topic in both science and engineering.
