In science, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.The law of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces the mechanical energy is constant.n science, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
As with the standing shin stretch, the cross-over stretch is well-suited for pre- and post-running stretching. You can perform this stretch with or without shoes. Start standing with your feet together. Cross your right leg in front of your left leg and place the tops of your pointed right toes on the ground.
1. Stretch. It's important to stretch your muscles before you dive into the cartwheel, or you may pull or strain a muscle. To prepare for a cartwheel, you should stretch your wrists, your ankles, and your hamstrings and inner thighs by sitting in a straddle position and reaching toward the ground in front of you.. Plant your second hand and straddle your legs in the air. Kick powerfully so your legs come off the ground. You'll be balancing your weight on your arms, using your shoulders and core for support, like a handstand, with your legs in the air in a v-shape, or a straddle.
