First day science
4. When playing basketball, volleyball and football, the force objects are human hands or feet, and the force objects are basketball, volleyball and football respectively. 5. objects can also exist forcefully when they are not in contact, for example, magnets will attract or repel each other. 6. skating, rocket launching and rowing are all pushed forward by the reaction force of driving forceDo the interacting forces occur simultaneously or in sequence? Two objects can interact without contact
A: (1) the forces between objects are interactive, and the two interacting forces are generated at the same time, for example, the foot feels pain when playing football, and the hand feels pain when pounding the desktop. (2) the force can also be generated when two objects are not in contact, such as magnets attracting nails, the interaction between magnetic poles, etc
Physics, mathematics
1. Newton n 2 Choose B because the forces act on each other! 3. both. As long as there is force, thMagnet playing football  volleyball and footballere is reaction! 4. the magnet attracts the paper clip. Interaction of forces properties of magnets Mathematics: 1 Let y1=m/x y2=kx (is it the square of X?) (m。
Flatten the sponge with force. The effect of the force is to change the shape of the object. The effect of the force of kicking the football is to affect the object
A. Kicking the ball out with force changes the state of motion from static to dynamic, so a meets the meaning of the question; B. The pressure causes the springboard to deform, so B does not conform to the meaning of the question; C. The tension makes the bow bend and deform, so C does not conform to the meaning of the question; D. The magnet attracts the small iron ball and changes the direction of movement of the small iron ballIt can convert the kinetic energy of football into electric energy when playing football
It can be seen Magnet playing football  volleyball and footballfrom the meaning of the topic that the football generator can generate electricity. It is a device that uses the Magnet playing football  volleyball and footballprinciple of electromagnetic induction to charge; A. The figure shows that a part of the conductor of the closed circuit can generate induced current by cutting the magnetic induction lineTwo magnets attract each other. Do they deform
In physics, it must be, but we can't see it with the naked eye. The reason is that both magnets are attracted by each other and have deformed In addition, the force can change the moving direction of the object. For example, when a person plays football, the direction of the football changes >There are two physical phenomena of force, light, sound, heat, electricity and magnetism
Force: the explosion increases the volume of gas in the bottle and pushes the piston. When you kick a ball with your foot, the ball changes from static to motion. Light: pinhole imaging. See the figure in the mirror (reflection of light). Sound: gas and oil explode in the cylinder. People hear all kinds of birds. Hot: gasoline burns in the engine. Combustion of combustiblesMiddle class math lesson plan playing football
-- how to make "soccer villains" play football—— Guide the children to discuss and inspire the children to move the magnet back and forth, so that the little people can move. Hold a football match—— Children can play the game of playing football on the "football field" with their own small people... So why does the force of the foot on the football disappear when the football leaves the foot
Or missed!? towards the left? towards the right? Or an own goal?) Gravity and air resistance counteract the inertia force, making the inertia disappear gradually, and then the ball falls to the ground. When you kiMagnet playing football  volleyball and footballck a ball, the football will have a reaction force on your feet, and the ball will balance the force on your feet and your foot pairsWho is the "magneto" in Croatia? Is he really magnetic
It is reported that Ivan · Stoilkovic is very similar to other local boys of his age in many ways - he likes playing football in his garden and is currently learning the accordion as his hobby. But it is incredible that Ivan · Stoilkovic has a magical power
