  1. 2*7 Notes (p212-214) • Analyzing the Forces Acting on the Shoe • When an object moves at constant velocity the net forces equal ZERO Constant Velocity = NO Acceleration = Balanced Forces = Net Force is ZERO = Arrows have SAME LENGTH!!!

  2. 2*7 Notes (p212-214) HORIZONTALLY • The shoe moved forward at a slow constant velocity, so there is equal and opposite force = FRICTION VERTICALLY • The shoe did NOT move up nor down, therefore the net forces must be BALANCED and EQUAL ZERO • Normal Force  acts perpendicular to the surface; it’s the force of the 2nd object

  3. 2*7 Notes (p212-214) 2. Coefficient of Sliding Friction, μ (μ) = force of friction = ← normal force ↑ • (μ) does NOT have units • (μ) expressed in decimals • A change in the SURFACE causes a change in (μ) • the rougher the surface, the greater the (μ) • The smoother the surface, the less the (μ)
