Physics playing basketball learning physics knowledge to save sports skills

How important is physical knowledge to physical education
In addition, in the process of playing basketball, there is a great relationship between the use of some strength and physical knowledge. For example, the forces are mutual, that is, when two people or two teams collide, in fact, the degree of injury of the two people is very large, and the difference is very closeIs there any scientific basis for good physics and good basketball
There is evidence. Basketball is the most popular one in physics. On the court, you can use the laws of physics you are studying to add new ideas to basketball. We saw some interactive programs or basketball games with parabolic motion and collision, energy and power. After seeing it, you should have a new understanding of sportsWhat phenomena are related to physics when playing basketball
There are too many physical phenomena in motion. For example, the ball thrown will have a parabola falling, indicating that there is gravity. When you receive a hard pass, your hand will hurt, which shows that the effect of force is mutual. You jump up by converting kinetic energy into gravitational potential energy, and fall by converting gravitational potential energy into kinetic energyWhat's a good birthday present for boys who like physics and play basketball
I think you should give away a basketball. Basketball is not expensive. A better one costs more than 100 yuan. Of course, you don't need to buy four or five hundred, because you usually play in the concrete. You like basketball. Of course, you should give away basketball. You can go to your local sporting goods store. It's not recommended to go to the exclusive store. It's too expensive. I also like playing basketballLife is closely related to physics For example, when you play basketball, the basketball you throw can fly in the air, which mainly
When the basketball is thrown, it obtains a speed from stillness due to the thrust of the hand and starts to move. When the basketball leaves the hand, it will no longer be under the force. However, because the object has the property of keeping the original motion state unchanged, that is, it has inertia, the object should keep the original motion state unchanged: physical principles of basketball dribbling
Dribbling is the most basic skill in basketball. Many beginners see some old hands dribbling. They seem to stick the basketball to their hands like glue, and they can let the basketball go at any time. When they do some dribbling, those old hands will change the ball to any direction according to their own needs at any timePhysical question: playing basketball is our favorite sport A basketball track thrown obliquely into the air
If D A is selected, if the balance force is at and the force balance is the resultant force is 0, then the ball will land under the action of the earth's gravity if it is either stationary or moving in a uniform straight line. If C is selected, the force is the reason for changing the motion rather than maintaining the motionHigh school physics, there are questions about shooting (oblique throwing)
Solution: suppose the angle between the shooting angle and the horizontal direction is 。 Horizontal direction: uniform linear motion vo*scos * T=s s=4 so t=? Vertical direction: uniform deceleration linear motion vosin = GT (the vertical speed at the highest point is 0) simultaneous, and Thank youWhat physical knowledge does basketball and football contain
Momentum theorem, kinetic energy theorem, law of conservation of energy, relationship between acceleration and velocity, Newton's first, second and third laws, law of universal gravitation, circular motion
Physics: how much pressure does the basketball exert on the ground when playing basketball? And design an experiment to measure_ Hundred
1. Now hit the ball with water on the paper, then put it on the scale, press it on the same paper until the size of the watermark is the same as before, and observe the reading of the scale, that is, the pressure of the basketball on the ground 2. strike marks on the flat sand and measure the depth of sand subsidence
