In the pascals triangle the upper two numbers must add up to the middle lower number.
In order for an object to be in constant uniform motion ... that is, un-accelerated, with constant speed and direction of motion ... the vector sum of all forces acting on it must be zero.
The principles of design are the rules a designer must follow to create an effective and attractive composition.
No matter what the mass is, there are two conditions for equilibrium:The sum of forces on an object must be zero.The sum of torques on an object must be zero.For actual calculations, each of these conditions usually translates to three separate equations.
Because of the principle of energy conservation the lost mass must reappear as generated energy, according to Einstein's equation E = mc²
