    Physics question on kinetic energy and momentum....?

    Okay this is question is confusing me. Kinetic energy (KE) has dimension kg * m^2 / s^2 and can be written in terms of the momentum (p) and mass (m) as: KE = (p^2) / 2m. a) Determine the proper units for momentum using dimensional analysis. So this is what I did so far: [KE] = [kg] * [m^2] /...

    Which is the hardest subject at Higher: Maths, Chemistry or Physics?

    organic chemistry was the hardest so far for me at college but I will be taking physics this year so I don't know yet. Math (pre-calculus and calculus) isn't hard.
