Activities under the theme of unity. Urgent. I hope you will give us valuable suggestions. Thank y

Absorb the essence of tradition to have a solid foundation; Only by reflecting the spirit of the times can we lead the fashion of the times. "Be proud of solidarity and mutual assistance, and be ashamed of harming others and benefiting yourself. This socialist concept of honor and disgrace not only further expounds the traditional virtues of the Chinese nation, but also highly summarizes the basic characteristics and requirements of the main social system in the new period.

As the saying goes: "A fence has three piles, and a hero has three gangs." "Solidarity and mutual assistance is the traditional virtue of the Chinese nation, and the thinkers and politicians of our country have all respected the concept of solidarity and mutual assistance

Historical experience has proven time and again that whether there is a moral habit of solidarity and mutual assistance is one of the important indicators for judging whether a group (collective) is healthy and whether a society is harmonious. We also often say:

Unity is strength. Solidarity and mutual assistance is to test the cohesion, combat effectiveness and create a ruler, a brick, only piled up together can achieve a high-rise building, a drop of water, only into the sea can be eternal! A person needs unity to achieve a career.

If a collective wants to win in the competition, a country, prosperity and strength need unity! The ancients said: The hearts of the people are united, and Mount Tai moves.

Solidarity and mutual assistance are the good qualities that contemporary students should have. It is the source of strength for the sustainable development of the school. Students in the new era should strive to cultivate their team spirit and the concept of mutual assistance.

Strive to: unite and help each other between teachers and students, and strive to create an excellent class body; All members of the school unite and help each other to create a brilliant tomorrow for the development of the school!

Collective pass table tennis activities, divided into two groups, with a spoon to pass the table tennis ball from one person to another, the ball can not be dropped halfway, at the specified time to see which group passes more.

Two people and three feet (the whole class together), that's how we play, we have to stick together....And tug-of-war is also good....

Suppose the object is moving to the right, the ground is rough, and there is no force on the object, and the direction of the frictional force it is subjected to is to the left, and it does a deceleration motion.

When the object is in deceleration motion, the direction of the resultant force is opposite to the direction of motion.

The direction of the resultant force is the direction of the acceleration of the object.

You can analyze the force on the object first, and then you will know the direction of the resultant force.

In general, the direction of the resultant force is inside the trajectory of the object's motion.

Generally, it is enough to draw the general direction.

Also, downstairs, the direction of the resultant force is not perpendicular to the direction of velocity, if it is a flat throwing motion, the direction of the resultant force has always been vertical downward, but the direction of its velocity is changing all the time.

Start by drawing the direction of velocity at a point, and (it's easy) the direction of the resultant force is perpendicular to the direction of velocity. As the book says, "The centripetal force always points to the center of the circle".

The direction of the resultant force points to the direction in which the object's trajectory is bent.

1. The sentence "The direction of the speed of the object's motion is always the same as the direction of the resultant force" is wrong!

The direction of the resultant force determines the direction of acceleration and is not necessarily related to the direction of velocity! Example: Uniform deceleration in a straight line, the direction of the resultant force is backward, then the direction of acceleration is backward, but the direction of velocity is forward until the velocity is reduced to zero.

2. "When the resultant force on an object is zero, the velocity must be zero." "Wrong, too!

The same can be explained by "the direction and magnitude of the resultant force can only determine the magnitude of the untitled acceleration, and there is no necessary connection with the direction of the velocity"!

When the net force experienced by an object is zero, the velocity is not necessarily zero. It is also possible to move in a straight line at a uniform speed.

Both sentences are wrong, it's junior high school physics.

The direction of the resultant force is the same as the direction of acceleration, but it can be the same as the direction of the object's motion, for example, when the object is decelerated by an external force, the direction of the resultant force is the opposite to the direction of motion.

The second sentence is that the net force on the object is zero, and it may be stationary or it may be moving at a uniform speed, provided that it is on a smooth surface.

Huh

Not everyone's achievements in this world are personal, and their success is the result of the sweat, tears and blood of thousands of people. Perhaps, when the Creator created humanity, he wanted us to understand the principle of unity, because He created a group of people, not a single person.

On the road of life, there will inevitably be setbacks, failures and difficulties. Sometimes it is not something that can be solved by the power of one person. It requires cooperation and solidarity.

Many times people need to be helped, maybe it is their own personality to be alone, but when you can't solve it yourself, you will suddenly find that it is so important to integrate into the group. The power of solidarity and cooperation is enormous, and it is enough to create miracles. They created the Great Wall more than twenty years ago.

It may not be their own will, but if they do not cooperate and unite, it is likely that the Great Wall will never stand on the eastern soil. Its creation condenses not only sweat, but also tears, blood, and hardship. Solidarity transcends pain and hardship.

When China's first mountaineering pair reached Mount Everest, they must have been joyful and proud. But behind the joy and pride are dissatisfaction with death and fear. At that time, the only thing that could transcend death and fear was solidarity and cooperation.

In fact, not only many big things, but also many small things also need to be united. Small productions require cooperation, and so does playing games. By playing games, we learn to cooperate, unity, learn to be collective, and integrate the strength of the individual with the collective.

The strength of ten or a few hundred people is amazing, because as the saying goes, the flame is high when people gather firewood. Therefore, when you encounter difficulties, don't forget that the collective is your reliance, and when the collective encounters difficulties, don't forget that you are a member of the collective. So the collective and the individual are inseparable.

We should learn to unite and cooperate.

Not necessarily in the direction of acceleration.

Isn't the uniform circular motion that the direction of motion of the object is not consistent with the direction of the resultant force of the external force on the object?

Answer, Zhi Li Yan held me and patted the circle.

The direction of the resultant force is the same as the direction of acceleration, but it is the same as the direction of motion, sometimes the same and sometimes the opposite.

In classical mechanics (Newtonian mechanics), f=ma, f, and a are all vectors, which represent the magnitude and direction, and f is the resultant force, from which it can be seen that the direction of the resultant force is the same as the direction of the resultant acceleration.

The direction of acceleration and the direction of motion have little to do with each other. The direction of acceleration is determined by the external force, which is the same as the direction of the external force; The direction of motion is determined by the direction of velocity. If the acceleration and velocity are in the same direction, the motion is in a straight line, and the velocity increases, the direction is opposite, and the velocity slows down; If the direction is not in the same straight line, it is a curvilinear motion, and the trajectory of the direction of motion is sandwiched between velocity and acceleration, bending in the direction of acceleration.

Examples are found on the Internet: flat throw, oblique throw, up throw, down throw, free fall......,

The direction of the resultant force is the direction of acceleration, and acceleration is the direction and magnitude of the change in the velocity of motion.
