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
