THE DESIGN PROCESS
STEP 1: Identify the Problem – State the problem in your own words STEP 2: Identify Criteria and Constraints – Identify the specific requirements THE DESIGN PROCESS
STEP 3: Brainstorm Possible Solutions – Discuss ways to solve the problem STEP 4: Generate Ideas – Each member comes up with their own plan STEP 5: Explore Possibilities – Group members discuss the various approaches THE DESIGN PROCESS

Fundamental forces of flight HOW PHYSICS CONTRIBUTES
For our consideration HOW PHYSICS CONTRIBUTES
momentum (P) = velocity (V) x mass (M) V = rate of travel (r) & direction r = distance (d) / time (t) d = 6 meters HOW PHYSICS CONTRIBUTES
V² = V₀² + (2)(a)(d) V² = 0² + (2)(9.8 m/s²)(6 m) V² = m²/s² V = m/s down = 24 mph down HOW PHYSICS CONTRIBUTES
V = m/s down P = V x M Mass is between g and 1000 g P = (10.84 m/s) x (.5 kg) P = 5.42 N*s HOW PHYSICS CONTRIBUTES
STEP 6: Select an Approach – Decide which approach to take STEP 7: Build a Model or Prototype – Construct a model based on the idea selected STEP 8: Refine the Design – Evaluate the product and decide if a redesign is needed and what to change THE DESIGN PROCESS
