The following sports belong to those sports respectively: the apple falls to the ground, the water is heated and evaporated, the peach blossom is in full bloom, and the canoe has passed through the Chung Shan Man light, and the friction is electrified. hello! The following is my answer to the question:

mechanical movement of apple falling to the ground

molecular thermal movement of water heating evaporation (just heat filling movement)

peach blossom blooming life movement

the canoe has passed the mechanical movement of Chung Shan Man (movement of relative change of spatial position)

straight-line propagation of light movement

triboelectrification movement

the spring in hand-elastic potential energy (mechanical energy Kinetic energy (one of mechanical energy)

fresh milk-chemical energy

lightning flash-light energy and electric energy

Shenzhou VI flying into the blue sky-kinetic energy and potential energy

various forms of energy can be converted to each other under certain conditions. Such as:

water flow to generate electricity (mechanical energy-electric energy)

running trams (electric energy-kinetic energy)

cooking with gas (chemical energy-thermal energy)

photosynthesis of plants (solar energy-chemical energy) (photosynthesis requires light energy and thermal energy)

You can often see "slow down" and "keep going" along the road.

a: because the road is slippery in rainy days, there is water on the road, and the roughness increases, which leads to the reduction of friction, and it is easy to cause traffic accidents if you don't go slow; However, keeping the distance between cars is because the emergency brake will produce inertia, resulting in a car accident.

what energy is stored in the bowstring when the bow is pulled? When you pull the bow, the arrow will shoot. What has happened at this time?

① elastic potential energy ② elastic potential energy is converted into kinetic energy

5. When an athlete jumps from the trampoline to the highest point, he has (gravity potential) energy, while he falls, he has (dynamic) energy, and when he reaches the lowest point on the trampoline, the trampoline has (elastic potential) energy (mechanical energy is ok, but not complete enough)

I tried my best! It happens that we are also learning this recently, so we can learn something new by reviewing the old ones! In some places, the teacher asked for details. The teacher has talked about these topics, so I wrote them according to the standard answers! I hope it helps you!
