How does Messi keep the ball close to himself

The science of how Messi keeps the ball close to himself photo credit: ZaleDesigns Messi is a magician with the ball at his feet. He's in my opinion the best player in the sense that he can control the ball so well, runs so fast with the ball & changes the direction at full speed like it's a walk in the park. For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion. Height He is short which means a low center of gravity so it's difficult to push him off the ball. That's why we see that anyone rarely can topple him down, instead players much larger than him lose possession to him. So his short height suits his style of play & is a blessing in disguise. Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...

Why Is Blood Red?

        why blood is red?



Blood is red because it is made up of red cells, often known as red blood cells. However, studying these cells at a molecular level is required to understand why they are red. Hemoglobin is a protein that is found in red blood cells. Hemes, which give blood its reddish color, are made up of subunits of each hemoglobin molecule.

IRON MAKES OUR BLOOD RED



Hemes (hemoglobin), in particular, have the ability to bind iron molecules, which then bind oxygen. Because of the interaction between iron and oxygen, blood cells are red. (It appears red because of how light is reflected by the chemical interactions between the iron and the oxygen.) And blood's ability to carry oxygen is critical because when blood flows through the lungs, it picks up oxygen and transports it to the rest of the body until the oxygen is depleted, at which point the blood returns to the lungs to obtain more oxygen.

what is friction?

Physics - Friction Introduction Friction  is result of the irregularities on the two surfaces in contact of each other. The force of friction is dependent on the irregularities of the surface; if it is greater, then the friction will be greater and if it is smooth, then the friction will be lesser. Effectively, the friction is result of the  interlocking  of irregularities in the two surfaces. If the two surfaces (in contact) are pressed harder, then the force of friction will increase. On a frictionless surface, if an object starts moving, it would not stop ever; Without friction, it is not possible to construct a building. Friction produces heat; when a matchstick is rubbed against the rough surface, it catches fire. Substances Reducing Friction The substances that reduce friction are known as  lubricants . E.g. when oil, grease, or graphite is applied between the moving part of a machine, then it creates a thin layer; resultantly, moving surfaces do not directly r...

why is force, what is pressure?

 Force and Pressure Introduction When an object is either pushed or a pulled is known as a force. Motion, generated in an object, is because of an action of a force. The applied force makes the table move in a given direction. The strength of a force is commonly expressed by the magnitude. Force also has direction; likewise, if the magnitude or direction changes, it directly affects the force. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object. If an object is in motion, then external force may change in the state or direction of motion of that object. The state of motion of an object is explained by its speed and the direction of motion. The state of  ‘rest’  of an object is considered to be the zero speed, as − An object cannot move by itself. An object cannot change its speed by itself. An object cannot change its direction by itself. An object cannot change by itself. A force may make ...

what are hormones?

Biology - Hormones in Animal Introduction Human body has different glands (as shown in the image given below) that secret Hormones (liquid substance), which are essential for the different body functions. Adrenaline Hormone is secreted from the adrenal glands. It is secreted directly into the blood and then carried to different parts of the body. On the other hand, plants have hormones that control and regulate their directional growth. Iodine is essential for the thyroid gland that makes thyroxin hormone. Further, Iodine is an essential element for the synthesis of thyroxin. Deficiency of Iodine, that might cause goiter. The term “goiter” refers to the abnormal expansion of the thyroid gland (resulting into swollen neck). Thyroxin Hormone regulates carbohydrate, protein, and fat metabolism in the body and provide the best balance for body growth. Growth hormone, which is secreted by the pituitary gland, regulates growth and development of the body. The deficien...
