Only really just started doing revision for this exam... It's a lot harder than I remembered it to be.
Despite only doing M1 last week, Kinematics/Statics feels so difficult.
Anyway, quick question. What's the difference between "The work done against Friction" and "The work done by friction". In two separate questions they ask this, but the particle is moving at constant velocity up the plane in both so I can't understand what the difference is and I expect it's either a mistake or they're the same?
Thanks
