How might gravity, inertia and Newton’s third law relate to PE safety? Give an example for each one.

Biomechanics in sport incorporates a detailed analysis of sport movements in order to minimise the risk of injury and improve sports performance. Sport and exercise biomechanics encompasses the area of science concerned with the analysis of the mechanics of human movement[1]. It refers to the description, detailed analysis and assessment of human movement during sport activities[2]. Mechanics is a branch of physics that is concerned with the description of motion/movement and how forces create motion/movement. In other words, sport biomechanics is the science of explaining how and why the human body moves in the way that it does. In sport and exercise, that definition is often extended to also consider the interaction between the performer and their equipment and environment. Biomechanics is traditionally divided into the areas of kinematics which is a branch of mechanics that deals with the geometry of the motion of objects, including displacement, velocity, and acceleration, without taking into account the forces that produce the motion while kinetics is the study of the relationships between the force system acting on a body and the changes it produces in body motion[1][3][4]. In terms of this, there are skeletal, muscular and neurological considerations we also need to consider when describing biomechanics[2].( Btw this is not mine own writing do not copyright me)

garcinia cambogia became popular worldwide after being featured on the dr. oz show in 2012.

it is a small, green fruit, shaped like a pumpkin.

the skin of the fruit contains hydroxycitric acid (hca). this is the active ingredient in garcinia cambogia extract, which is marketed as a diet pill.

how it works: animal studies show that it can inhibit a fat-producing enzyme in the body and increase levels of serotonin, potentially to reduce cravings (1, 2trusted source).

effectiveness: one study with 130 people compared garcinia against a dummy pill. there was no difference in weight or body fat percentage between groups.

a 2011 review that looked at 12 studies on garcinia cambogia found that, on average, it caused weight loss of about 2 pounds (0.88 kg) over several weeks.

side effects: there are no reports of serious side effects, but some reports of mild digestive problems.
