What is uphill energy?
Gravitational energy is when an object has more potential energy because of its higher or up hill position. An object rolling down a steep hill will have more energy than one from a lower position.
Is pulling a wagon uphill an example of increasing potential energy?
Yes, the gravitational potential energy is increased. The potential energy in joules is equal to mgh (mass * gravity * height), so increasing the height increases this energy.
What energy is used for travelling uphill?
Kinetic energy
Do underground streams sometimes flow uphill?
They could in theory.
Gravity your kinetic energy when you are driving uphill and it when you are driving downhill?
it is both kinetic and potential energy
What is a shape slope uphill called?
Skandahar
What energy conversion takes place when you run after a meal?
Chemical energy into heat and kinetic energy. Potential energy too, if you move uphill.
What type of reactions are considered uphill?
Anabolic because it requires the input of energy.
Why does walking for one kilometre uphill use more energy than walking for one kilometre on a flat road?
you exert more energy going uphill because your muscles strain a bit more but it really depends on the angle
Why do roller coasters end lower than where they start?
Since the top of the first hill is the highest point on the track, it's also the point at which the roller coaster's gravitational potential energy is greatest. As the roller coaster passes over the top of the first hill, its total energy is greatest. Most of that total energy is gravitational potential energy but a small amount is kinetic energy, the energy of motion. From that point on, the roller coaster does two things with its energy. First, it begins to transform that energy from one form to another--from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic energy increases. Each time the roller coaster goes uphill, its kinetic energy decreases and its gravitational potential energy increases. But each transfer of energy isn't complete because some of the energy is lost to heat and sound. Because of this lost energy, the roller coaster can't return to its original height after coasting downhill. That's why each successive hill must be lower than the previous hill. Eventually the roller coaster has lost so much of its original total energy that the ride must end. With so little total energy left, the roller coaster can't have much gravitational potential energy and must be much lower than the top of the first hill.
How do you store electrical energy from solar panels?
You can store it in a battery or by pumping water uphill.
Can water flow uphill hypothesis?
Water can defy the force of gravity and flow uphill. This is possible when a device called a hydraulic ram is used. A wick action such as a rope can cause the water to flow uphill.
