Family Guy: Call A Scientist
• Physics → Gravity → Defying Gravity

Peter jumps up in excitement after hearing that he can keep the company plane. He defies the laws of gravity by staying in the air after his jump.

Public Discussion Questions

1. (NOS): Draw/describe what comes to mind when you hear the word "scientist."
2. (Laws/forces): Using Newton's laws and free-body diagrams, explain how Peter getting stuck in the air contradicts physical laws.
3. What is gravity? What causes gravity? What are ways in which we can "oppose gravity?"

Standards

• 5-PS2-1
Next Generation Science Standards
Support an argument that the gravitational force exerted by Earth on objects is directed down.

I used this clip when teaching about free-fall and projectile motion. Students forget that at the top of the parabola for a projectile a is still -9.8 m/s/s; the common answer is "0 m/s/s." This clip helped in the discussion of why that "0" isn't correct. and that really it's v that is 0 m/s. If v and a were both 0, then what happened to Peter would take place.
