What is Three Seconds? What is the difference between the first three seconds and the first three se

The easiest. Three-second violations are divided into three seconds for defense and three seconds for offense.

Defending for three seconds: If a defender stands in the three-second zone and has no offensive players at a distance of about 1 meter from the start, and he stays in the three-second zone for more than three seconds, he will be deemed to have defended for three seconds, and if he violates the rules twice, he will be punished with one penalty and one execution.

Offensive 3 seconds: If an attacking player stays in the 3-second zone for more than 3 seconds without the ball or with offensive action or intent, it will be regarded as attacking for 3 seconds and will be punished for exchanging the ball!

Take Yao Ming's defense of Ao Fat as an example. If Ao Fat stands outside the 3-second zone and gets stuck in Yao Ming's ball, Yao Ming is squeezed into the 3-second zone, and Yao Ming can stay in the 3-second zone for more than 3 seconds during this defensive process. If Ao Fat is outside the 3-point line, and Yao Ming does not defend others, but just stands in the 3-second zone by himself, then if he stays for more than 3 seconds, he will be blown for defending for 3 seconds.

3 seconds".

1. When a team is in control of the ball, the players of that team shall not stay in the opponent's restricted area for more than 3 seconds.

2. All lines in the restricted area are part of the restricted area, and any line touched by the team members is considered to be in the restricted area.

3. The 3-second limit applies in all throw-ins. It is calculated from the moment the throw-in player can handle the ball (the ball enters play) outside the bounds.

4. The 3-second limit does not apply to:

1. When the shot ball is in the air.

2. When grabbing rebounds.

3. Dead ball scored.

5. When a player stays in the restricted area for nearly 3 seconds, he may acquiesce to his dribble and shoot.

Violation of this rule is a violation.

Note: There is no violation of this rule if a team does not possess the ball.

Players who are heavily defended.

A ball-handler who is heavily defended (within a normal step) has 5 seconds to pass, throw, roll or dribble.

Violation of this rule is a violation.

This is when the defender stays in his side's three-second zone for more than three seconds.

These are all representations of a period of time, the difference is:

1. Within three seconds: refers to the first three seconds, that is, from time 0 to the end of the third second, including 0-1-2-3 (s).

2. Within the third second: It refers to the beginning of the third second and the end of the third second. That is, from the end of the second to the end of the third.

Time refers to a period of time, such as 2 seconds, that is, 2 seconds have passed. Moment refers to a point in time, such as 7:15:20 seconds, the third second is the end of the second second to the end of the third second, which is a period of time, and the end of the third second is the time point, which is also the beginning of the fourth second. The last three seconds are a period of time.

The distance is the length of the path of motion, and the displacement is the straight-line distance from the position to the end position. If you do a straight line and don't go in the opposite direction, then the distance is equal to the displacement, and the rest don't want to wait.

Difference between time point and time period:

First, the meaning is different.

1. The so-called time point is also called a blind spot in time and space, that is, the moment is a moment in time, or a point in the time axis.

2. Time period refers to the time course experienced between two different states of objective material motion. A time period is the time difference between one point in time and another.

Second, the characteristics are different.

1. The point of time is stationary, and any matter is moving due to the movement of time, and the object in the blind spot, which is the point in time, will not change.

2. The granularity of the time period usually used in the time period is days, weeks, tenths, months, quarters and years.

Three seconds is a time period and the first three seconds of the range are specified. It is a time, the time period before the start of the specified time in the first three seconds, and the range is specified.

The time that is so short that it is almost close to zero is called immediate, and instant means instant. Moments are not the same as time. For example, at what moment did the event take place?

How long did the incident last? These are two different concepts, and we should distinguish between the concepts of the end of the first few seconds, the beginning of the second, the end of the second, the beginning of the second, and so on, and the idea of the time after the first few seconds, the few seconds after the second, the few seconds, the first few seconds, and so on.

Time and time are described by an infinitely long line with arrows that only indicates order and not direction, and this line with arrows is called the timeline. Each point on the timeline represents a moment in time.

Time is a measure of the order of movement of all matter, it has no length, only sequence, it is an ordinal number. The length of the interval between the corresponding two moments on the timeline represents a period of time, and time is a physical quantity with only length and no direction. Time is continuous, unidirectional, sequential, and always moving forward.

The length of the interval between the corresponding two moments on the timeline represents a period of time, and time is a physical quantity with only length and no direction. Time is continuous, unidirectional, sequential, and always moving forward.

In terms of words, moment can be used as a noun, such as an exciting moment, etc. In addition, moment can also be used as an adverb to describe a verb, such as we often say always ready, etc.

Within three seconds, a line segment is represented on the timeline, which is time, and the first three seconds are separated by 3 seconds (between 1 second and 3 seconds) A point is listed on the timeline, which is the moment, which represents the point of the first three seconds of the moment (the first 3 seconds of 5 seconds are 2 seconds).

The third second refers to the interval of time, which represents a period of time.

Time intervals and moments are collectively referred to as time, and it is not wrong to say that it is time. 0 3s, the first 3s, the third s, these are time intervals. 3s, the end of 3s, the beginning of 4s, these are moments.

A moment is a point in time, it has no length, it is like a point in a straight line, and the third second refers to the third second, that is, it has a length, and the length is 1 second.

Relationship with space

Space makes things changeable, that is, because of the existence of space, things can change or change. Space is something without energy, that is, when things can change, the energy generated by the change has canceled each other out with the energy that hinders it. The description of a point changing in space is called the time when the described point is equivalent to the point (when the point moves to a certain position, the described point will have a unique corresponding position, which is called the position of the described point at this time).

The third second is from the end of the second to the end of the third.

Moment refers to a point in time, such as 7:15 minutes and 20 seconds, the third second represents the end of the second second to the end of the third second, which is a period of time, and the end of the third second is the point of time, which is also the beginning of the fourth second. The last three seconds are a period of time.

The time interval is the part between two points in time, that is, the length of the interval. The time interval can only show one process of movement, and the moment can only show one moment of movement. A poem that is written about time intervals and moments can be understood correctly.

Such as the end of the 4s, the 4s, the 5s ......It's all moments; ...... within 4s, 4s, 2s to 4sThey are all delayed in time.

Within three seconds: It refers to the beginning of the third second and the end of the third second. A precedent for 3-second violations in basketball.

Three-litre refraction: Generally refers to a basketball game.

The offense is a three-second violation.

Defend three seconds with a violation. Defending a three-second violation is a rule unique to the NBA.

Defend for three seconds1. The timing begins when the attacking team controls the ball in the front court.

2. Any defensive player who is in a 16-foot penalty area or an area that extends 4 feet beyond the baseline must be in active defense of an opposing player for three seconds. Active defense means being no more than an arm's length away from an attacking player and being in a defensive position.

3. Any defensive player can defend any offensive player. Defenders can double up on any player.
