Question

this model shows the different positions of a person on a swing. consider each of the energy graphs (a-c). which one most accurately shows the energy of the person at position 1? a graph a b graph b c graph c d none of the graphs are accurate for position 1.

Explanation:

Position 1 on a swing is likely the highest point (like the top of the swing's arc). At the highest point, kinetic energy (KE) is minimum (near zero, as speed is zero) and potential energy (PE) is maximum.

• Graph A: KE and PE seem equal? No, at highest point KE should be low, PE high.
• Graph B: KE is low, PE is high. This matches the energy distribution at the top of the swing (position 1).
• Graph C: KE is high, PE is zero? That would be at the lowest point (not position 1).
• Option D is incorrect as Graph B is accurate.

Answer:

B. Graph B
