the skateboards potential energy becomes kinetic energy and heat energy.
no
It is a direct relationship. When temperature goes up, energy goes up. When temperature goes does, energy goes down.
It goes left
The skier going up the hill gains potential energy due to its height increase, which is stored energy that can be released when the skier goes back down the hill. As the skier goes down the hill, the potential energy is converted into kinetic energy, which is the energy of motion.
Which ever way the traffic goes
A salamander is a cold blooded animal. So it simply follows the temperature change. Temperature goes down, its body temp goes down, Temp goes up its body temp goes up
potential energy
the food that we eat, it goes to the mitochondria where it is broken down into energy.
When thermal energy is added the matter goes slower
Well, if for turbo skateboard you mean a skateboard that goes really fast, then the answer is yes! It all depends of the type of wheels you are using, the trucks and how loose or tight they are, the material of the skateboard, the strenght you put on your toes when impulsing and the ground where are you skating.
You hold the board don the either side at the tip, but you still have grip on it. You then throw it low and plant your feet on it before it lands then keep your balance when it goes down.
First off an assumption: dissipative forces are negligible - this means no energy goes into overcoming friction and air resistance. It also means that the total energy of the system "U" is a constant. The total energy is the sum of the kinetic and potential energies: U=Ke+Pe Potential energy is a function of height and mass, kinetic is a function of mass and velocity. So at the top when the skateboard isn't moving: Ke=1/2mv2 =0 as velocity =0 Pe=mgh U=Pe+0=mgh Where h is the full height of the ramp. Halfway down the ramp the height =h/2 so Pe=mgh/2 Remembering U must be the same as it was at the top of the ramp: U=mgh=Pe+Ke=mgh/2 +Ke So solving gives Ke=mgh/2.
