How do you subtract vectors?
it depends on the method of subtraction. If the vectors are drawn graphically then you must add the negative of the second vector (same magnitude, different direction) tail to tip with the first vector. If the drawing is to scale, then the resultant vector is the difference. If you are subtracting two vectors <x1, y1> - <x2, y2> then you can subtract them component by component just like scalars. The same rules apply to 3-dimensional vectors
What is three D shapes?
3D shapes are three dimensional, just like 2D shapes are two dimensional.
Resultant of two like parallel forces?
The magnitude of the resultant of two like parallel forces is the sum of the magnitudes of the forces and its direction will be same as the direction of the parallel forces.
What is an example of 2 and 3 dimensional shapes?
Well two dimensional means a flat shape, like a square, or a circle. A three dimensional shape means you can hold it, like the 3-D version of a square is a cube, and a 3-D circle is a sphere.
What is a 2 dimensional shape?
It is something that can be drawn on paper, like lines and curves, triangles and squares and circles, and so on. The next level up is three dimensional which is like boxes and balls.
