Why does a person's kinetic energy decreases as they enters water?

Yes , because when you enter water, it's density is 1,000kg so it makes it harder to walk and run.

What would increase a temperature of a substance?
When a substance is heated the temperature is increased. This occurs because energy enters the substance which will increase the kinetic energy of the molecules,thus causing a rise in temperature.
Describe a case in which electrical energy is converted into thermal energy?
hair dryer, electrical energy enters the hair dryer and is converted to kinetic energy as a small motor spins a fan blade the electrical energy is converted to thermal by a grind of wires that heat up
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
Why do particles carried by a river settle to the bottom as the river enters the ocean?
Because the velocity of the river water decreases as it enters the ocean.
Most energy that enters electron transport enters as?
FADH2 and NADH
When a space vehicle re-enters the Earth's atmosphere energy is turned into energy?
kinetic and heat
What energy transfer takes place when steam enters the turbin housing?
i believe it is chemical to kinetic but there is probably no transfer becasue chemical energy is stored energy like in a battery, but steam is i guess kinetic cuz its moving, and turbines definitely are kinetic due to movement, so probably no energy transfer.
How does a wind turbine make energy from wind?
Wind contains kinetic energy. When the wind enters the turbine, the kinetic energy is converted to mechanical energy. Then the energy goes through a generator that makes it into electrical energy (electricity).In simpler terms:The wind passing the blades of the turbine spin the shaft that is connected to the generator (kinetic to mechanical energy conversion). The spinning generator produces electricity (mechanical to electric energy conversion).

When energy enters a substance what is it called?
The electrons of different atoms start moving due to the change in kinetic energy. This produces a rise in the temperature of the substance. Each substance will have different reactions to the temperature changes{THIS WAS NOT MY ANSWER}

How does a roller coater changes speed?
as the rollar coaster goes up the "hill" as far as it can go , it is considered. Once there it goes down hill and becomes kinetic energy. The roller coaster changes speeds because of the series of hills it goes up and falls down. At the top of the first lift hill (a), there is maximum potential energy because the train is as high as it gets. As the train starts down the hill, this potential energy is converted into kinetic energy -- the train speeds up. At the bottom of the hill (b), there is maximum kinetic energy and little potential energy. The kinetic energy propels the train up the second hill (c), building up the potential-energy level. As the train enters the loop-the-loop (d), it has a lot of kinetic energy and not much potential energy. The potential-energy level builds as the train speeds to the top of the loop (e), but it is soon converted back to kinetic energy as the train leaves the loop.
When a ray of light from air enters to glass what happens to velocity?
it decreases
What is kineticpotential energy?
Kinetic and Potential energy are totally different. An object has potential energy because it has the potential to change the states of objects in the system when the energy is released. Kind of vague, but examples will help. An object on the top of a mountain has potential energy that could be used if the object falls off the mountain. As it falls it acquires velocity, which is kinetic energy. The kinetic energy of an object is the extra energy which it possesses due to its motion. Objects can change their energy between these two types of energy. An example is a glider at 20000 feet. It has potential energy due to its height. It also has kinetic energy due to its forward speed. if the glider dives, it acquires more speed, ie, more kinetic energy while losing potential energy. In other words, potential energy is changed to kinetic energy. As it gets close to the ground, it uses its forward speed to zoom back to a higher altitude. Here kinetic energy is converted back to potential energy. Another example is Hoover dam. Water is stored at a high level. To generate electric power the water enters a pipe that routes the water down to the generators at the bottom of the dam. Potential energy of the water (from its height above ground) is changed to kinetic energy as it flows down the pipe and speeds up. When it hits the water turbine it is moving quite fast (lots of kinetic energy). The water hits the blades of the turbine and makes the blades spin, transferring the kinetic energy of the water to angular kinetic energy of the turbine. This is directly coupled to an electric generator which converts the angular kinetic energy to electrical enrgy.
