Why do heavier objects travel downhill faster?

Heavier objects travel downhill faster because they have more mass, which means they have a greater gravitational force acting upon them. This force causes them to accelerate at a faster rate than lighter objects, making them move downhill more quickly. Additionally, heavier objects may have a greater amount of momentum, which also contributes to their higher speeds when moving downhill. However, other factors like friction and air resistance can slow objects down, so the effect of mass alone may not always be the determining factor in how fast an object travels downhill.
