Algebra is an area in mathematics that uses variables, in the forms of letters and symbols, to act as numbers or quantities in equations and formulas. Geometry is an area in mathematics that studies points, lines, varied-dimensional objects and shapes, surfaces, and solids.
Explanation:
It is your own opinion on which is more difficult. In my opinion, Geometry is more difficult.
Answer: I believe they want you to know the variables; and Newton described what? Force, action, mass.
I think you should read the Laws, and see how the variables, those important pieces, are shown in an equation. That will be of real help to you. Get the very basics down in your head (and on paper), and it will be much easier!
