Jump Around, Jump, Jump, Jump Around
This picture is of my friend Tori and me. My friend Skye needed jumping pictures, so Tori and I were nice enough to help him out, with our books, backpacks, laptops and all. In class this week, we were shown examples that displayed that an increased contact time decreases the amount of force on an object. This was shown with the boxers. If the boxers moved with the hit, the impact of the force of less because the contact time was longer. In this picture, when Tori and I landed, we bent our knees. This increases the contact time and like the car and the crumple zone, allowed for some give and distribution of momentum. If he had landed flat footed and legs straight, the momentum would've been stopped suddenly and would be bad for our knees.
