By 2*2*2 = 8
If the linear dimensions of a square or a rectangle are doubled, the area of the object will be quadrupled.

An object that exists in three dimensions is called a solid.
If the height of a cube doubles and the new object is to remain a cube, all its other dimensions must also double. The volume then increases by a factor of 23 = 8. If only the height doubles, the cube changes to a square prism, and in that instance, the volume doubles.
I think you are asking "What is a scale model"?
If the linear dimensions of a square or a rectangle are doubled, the area of the object will be quadrupled.
As force of gravity is directly proportional to the mass as mass is doubled then force on it also gets doubled.
two
Scale factor
Technically the answer is 0, as a rectangle is a 2-dimensional object that has no volume. However I expect that you mean a rectangular prism, so the volume of that would go up by a factor of 8 (2 to the power of 3).
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
[object Object]
If you doubled the force on a moving object you would double its acceleration.
It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v
The acceleration increases.
the kinetic energy of the object
An object that exists in three dimensions is called a solid.
