Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed.
Sports biomechanics is the quantitative based study and analysis of athletes and sports activities in general. It can simply be described as the physics of sports. Within this specialized field of biomechanics, the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement.
Hoop rolling, also called hoop trundling, is both a sport and a child's game in which a large hoop is rolled along the ground, generally by means of an object wielded by the player. The aim of the game is to keep the hoop upright for long periods of time, or to do various tricks .
It is the force which makes an object move over the surface by overcoming all the resisting forces like friction, normal loads (load acting on the tiers in negative Z axis), air resistance, rolling resistance, etc.
A roll is the most basic and fundamental skill in gymnastics class. There are many variations in the skill. Rolls are similar to flips in the fact that they are a complete rotation of the body, but the rotation of the roll is usually made on the ground while a flip is made in the air with the hips passing over the head and without any hands touching the ground.
Strength training, also known as weight training or resistance training, involves the performance of physical exercises that are designed to improve physical strength. It is often associated with the lifting of weights. It can also incorporate a variety of training techniques such as bodyweight exercises, isometrics, and plyometrics. [1]
Spotting is a technique that is often used when executing turns, in which a performer executes a periodic, rapid rotation of the head that serves to fix the performer's gaze on a single spot, thus giving the impression that the head is always facing forward. Spotting prevents dizziness by allowing the head to remain stable during most of the turn.
Adapted physical education is the art and science of developing, implementing, and monitoring a carefully designed physical education. Instructional program for a learner with a disability, based on a comprehensive assessment, to give the learner the skills necessary for a lifetime of rich leisure, recreation, and sport experiences to enhance physical fitness and wellness.
