This question needs more clarification - "turn over" needs defined better.
That being said, this most likely depends on the orientation and type of triangle. If the triangle is equilateral and rests on its base, it will be easier to turn over than the square because there is less mass toward the top, making it easier to turn it onto it's other side. If it were an isosceles triangle resting on one of it's longer sides, it would be more difficult to turn over because there would be mass around which to turn the outside of the triangle. In any case, as stated above this will ultimately depend on the definition of "turn over," the size and the type of triangle.
because of the weight and material that is used in the making of the object
The weight of an object can be affected by both the force of gravity acting on it and the mass of the object itself. In simpler terms, heavier objects have more weight because gravity pulls harder on them.
Friction is the resistance to motion when an object moves across another surface, while weight is the force exerted on an object due to gravity. Friction depends on the roughness of the surfaces in contact and the force pressing them together, whereas weight depends on an object's mass and the acceleration due to gravity.
Adding weight to an object can make it harder to move because the increased weight creates more resistance against the force needed to move it. This can require more effort or force to overcome the added weight and move the object.
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/volume)
100 grams is its mass, whatever the shape.
Well, darling, a triangle can hold as much weight as the materials it's made of can support. It's all about the strength of those sides and angles, not some magical weight limit. So, if you're planning on balancing a truck on a paper triangle, I suggest you rethink your life choices.
Not necessarily. The hardness of an object refers to its resistance to scratching or deformation, while the weight refers to the force of gravity acting on the object. An object can be hard but lightweight, or soft but heavy.
Because triangles distribute the weight to the sides of the bottom of the triangle allowing it to hold more weight than if it were a square
The weight of an object decreases as it moves farther away from the center of the earth due to the inverse square law of gravity. This means that the gravitational force acting on the object weakens as the distance increases.
It certainly does. That's why you have to push it harder to accelerate it horizontally. But that "more weight" that it has is exactly the more force it needs for vertical acceleration, and that's why all objects fall with the same acceleration.
The weight of an object affects its ability to slow down because a heavier object has more inertia, making it harder to stop. This means that more force is needed to slow down a heavier object compared to a lighter one. Additionally, factors such as friction and air resistance also play a role in slowing down an object.
