  Move It! ExploringTranslational and Rotational Motion Performance Task in Physics
• 2.
  Standards • Content Standard: •• Understanding linear and angular quantities to describe motion. • Learning Competency: • • Compare and contrast translational and rotational motion in terms of their respective linear and angular quantities.
• 3.
  Objective and Materials •Objective: • • Demonstrate the difference between translational and rotational motion using simple materials. • Materials: • • Toy car or box • • Circular lid or cap • • Ruler or measuring tape
• 4.
  Part A: TranslationalMotion • 1. Mark a 1-meter track. • 2. Push toy car in straight line. • 3. Measure time with stopwatch. • 4. Compute Speed = Distance / Time
• 5.
  Part B: RotationalMotion • 1. Roll lid along 1-meter path. • 2. Count full rotations and time. • 3. Measure diameter → compute C = πd. • 4. Compute θ = Distance / Radius. • 5. Compute ω = θ / Time.
• 6.
  Sample Computation • TranslationalMotion: • • Distance = 1 m, Time = 2 s → Speed = 0.5 m/s • Rotational Motion: • • Diameter = 0.08 m → Radius = 0.04 m • • θ = 1.0 / 0.04 = 25 rad • • ω = 25 / 2.0 = 12.5 rad/s

  Guide Questions • 1.How did translational and rotational motion differ? • 2. What quantities describe each motion? • 3. Did the rotating object also move forward? • 4. Why is it useful to understand both motions?
