Jumps

Parachute and terminal velocity

---

This animation reproduces what it is like to jump with a parachute. Observe what happens to the speed before and after opening the parachute. Can you explain what forces act in each case?

"Bungee jumping” without loss of energy

---

This simulation represents the jump of a person held by an elastic rope without loss of energy. When the fall begins, the person's speed accelerates until the tension of the rope holds him/her and propels him/her upwards. Observe how the Gravitational Potential Energy (GPE), Kinetic Energy (KE) and Elastic Potential Energy (EPE) vary. Why doesn't the movement stop?
