that passing the gravity crosses the edge of the car wheels. in that case, the truck would tip over.
“formula 1”, on the picture, center of gravity is between the car’s wheels and it is very low near the ground. this ensures that it does not tip over during a quick ride.
example 2: the picture shows one book in two different positions. the book is more stable in a position when a larger surface touches the surface, which is the case where the center of gravity is closer to the earth.
the chair is more stable with four legs than three legs. the reason for that is because the larger surface is
