If a cat that has a mass of 4.50 kilograms sits on a ledge that is 0.800 meters above ground and it jumps down to the ground, it will have a specific amount of kinetic energy just as it reaches the ground. In this instance, the answer would be 35.3J.
yes, as long as the wire is off the ground, the bird will have gravatational energy as it has the possibility to do something while falling. One could even argue that a bird flying has both kinetic and gravatational potential energy. i hope that clears things up!
Bees cannot be constantly flying, similarly humans cannot constantly run. There is simply not a large enough energy supply.
The vast majority of organisms that are designated as producers (generally plants) derive their energy from the sun through photosynthesis. Some exceptions to this are called extremophiles, which gain energy through chemosynthesis (such as bacteria around deep ocean vents).
a cat that's on the ground
because the area of their feet, that touches the ground, is large and so the pressure the elephant makes onto the surface of the ground is small. They will sink if the ground is not hard enough, but on average they have no problems with sinking into the ground
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
When a mass reaches the ground it will have a lot of potential energy installed inside. at the moment of hit all the potential energy is transformed into kinetic one. According to the type of the object the kinetic energy will act. if elastic it will jump up the same distance it fell (if free fall). .....
When it moves it has kinetic energy. And when it is above the chosen reference level (for example, above ground level), it has potential energy. A common practical situation is that an object falls down. When it starts falling, it has only potential energy; when it reaches ground level, it has only kinetic energy. At any point in between it has both.
the potential energy of sky diving is while you are in mid air your body is relaxed and the kinetic energy is when you have to pull the parachute to keep him up in the air before he reaches the ground

When ball is in the hand, it possesses internal energy. We give it kinetic energy when we throw it up and its kinetic energy decreases as it gains height.The kinetic energy turns to gravitational potential energy which reaches its maximum when it reaches its highest point. At that point the ball stops and then it falls.Its gravitational energy turns to kinetic energy as it falls. When it falls, its some energy turns to heat energy.When the balls hits the ground sound energy is produced and heat is given. The final energy which the body possesses is internal energy.
Tide = Flow of kinetic energy from higher ground to lower ground Wind = Flow of kinetic energy from higher pressure to lower pressure Electricity = Flow of electrical energy (transfer of kinetic energy) from higher voltage to ground or low voltage.
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
Tide = Flow of kinetic energy from higher ground to lower ground Wind = Flow of kinetic energy from higher pressure to lower pressure Electricity = Flow of electrical energy (transfer of kinetic energy) from higher voltage to ground or low voltage.
Once the object has reached the ground, its kinetic energy is zero.
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
Basically, if it moves, it has kinetic energy. And if it is above ground level, it has gravitational potential energy.
