- Review | Constants | Periodic Table Notice chge foet anation whes aking off and landing Hopping is an efficient method caf locomotion for the kangaroo (see the figure above). When the kangaroo is in the air, the Earth-kangaroo system has a combination of gravitational potential energy and kinetic energy. When the kangaroo lands, its Achilles tendons and the attached muscies stretch-a form of elastic potential energy. This elastic potential energy is used along with additional muscle tension to launch the kangaroo off the ground for the next hop. In the red kangaroo, more than 50% of the total energy used during each hop is recovered elastic potential energy. This is so efficient that the kangaroo's metabolic rate actually decreases slightly as its hopping speed increases from 8 km/h to 25 km/h. The horizontal and vertical force components exerted by a firm surface on a kangaroo's feet while it hops are shown in the figure.
