It is larger than all sorts of things. What you are probably referring to is that it is larger than the planet Mercury.
SUV (sports utility vehicle)
Vehicle code
No, it is not necessarily true that larger things have smaller volume compared to smaller things. The volume of an object is determined by its dimensions and can vary depending on the shape and size of the object. Larger things can have larger volumes than smaller things if their dimensions are proportionally larger.
obtuese
Yes, they have larger braking surface/weight of vehicle, than a car.
microscope
Not necessarily. The velocity of an object depends on factors like force, mass, and acceleration. Larger masses can have higher velocities if a greater force is applied to them, but they could also have lower velocities if the force is insufficient.
The kinetic energy of a vehicle is directly proportional to its mass and velocity. A larger vehicle will have more kinetic energy than a smaller vehicle traveling at the same velocity. This means that a larger vehicle will require more distance to come to a stop compared to a smaller vehicle, all else being equal.
a box that you can put things in to appear larger than what it is
If it is larger than 16,000 gross vehicle weight, it does.
An suv can hold more people in it, which is great if you have a larger family. It will also hold more groceries and bags, which is more economical than using a car and driving more to get things.
