According to Education.com, the pull of gravity acts more on an object rolling down a ramp inclined at a steeper angle, hence causing it to accelerate and move faster. For Dummies explains that when objects are rolling down an inclined plane such as a ramp, a component of the force of gravity causes it to accelerate downward.
When the ramp inclines toward the direction of the pull of gravity, an object on the ramp rolls at an acceleration that nears the full force, according to For Dummies. Any object on or near the surface of the earth experiences a constant pull of gravity that is directed straight down. When the object is on a ramp, it does not experience the full straight-down pull of gravity. As Education.com explains, experiments on a ramp do not measure acceleration of gravity, which is typically measured as 9.81 m/s^2.
As The Physics Classroom explains, a tilted surface is defined as an inclined plane in physics. An object on it naturally rolls downward, with its speed being affected by the degree of tilt. An object on a more tilted surface rolls down it at a faster rate.
According to For Dummies, at the point where the ramp is most tilted towards the direction of gravity, the greatest pull of the force acts on it.
