  1. Resistive Force and DiffEq

  2. Resistive Force • Always acts opposite the direction of motion • Friction, Air Resistance • You will be given an equation for air resistance (drag force) in the problem • Depends on the velocity

  3. A ball is dropped from a height. The drag force (Fd) is bv. What is the terminal velocity? Fd = bv At terminal velocity, Fnet = 0 Fg = mg

  4. A ball is dropped from a height. The drag force (Fd) is bv. Find the function for v(t) before it reaches terminal velocity? Fd = bv Fg = mg

  5. A ball is dropped from a height. The drag force (Fd) is bv. Find the function for v(t) before it reaches terminal velocity? Fd = bv Fg = mg
