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

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 = 117.6 m²/s²
V = 10.84 m/s down = 24 mph down
HOW PHYSICS CONTRIBUTES
V = 10.84 m/s down
P = V x M
Mass is between 226.8 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
