, θ = angle between F and the lever arm. (Max force at sin90° = 1) By convention, clockwise rotation is
negative, counterclockwise rotation is positive.
QUESTION 9
Work-Energy Theorem
CORRECT ANSWER
QUESTION 10
Kinetic Energy
CORRECT ANSWER
SI Unit for KE (all energy) = Joules = kg∗m²/s²
QUESTION 11
Work
CORRECT ANSWER
θ = angle between F and the displacement vector. Only forces (or components of forces) that are parallel
or anti-parallel to the displacement vector will do work. Max work at cos0 or cos180 = 1 or -1.
