When you move your hand or foot your body has converted potential energy into what type of energy?
Isn't the answer kinetic energy or something along the lines of that? I'm an eighth grader with a basic understanding of energy, and that's the first that comes to mind....
What are 2 types of energy sources?
First, energy sources are usually split into kinetic and potential. Kinetic energy is the energy of something in motion: the earth in orbit about the sun has kinetic energy. The earth also has kinetic energy due to its rotation. The moon orbiting the earth has kinetic energy, but the moon does not rotate. A car zipping along the highway has kinetic energy as does a train moving on a track. Potential energy is something which can become energy. A rock resting on top of a building can fall off the edge and gravity will pull it downward faster and faster. We say it had potential energy on top of the building's gravity well and this became kinetic energy as it fell. When the rock strikes ground, its kinetic energy will convert to thermal energy warming it and the earth beneath it. Other forms of potential energy include water held by a dam, a gas which has been compressed, and chemicals which can react, such as chemical batteries.
Examples of both kinetic and potential energy?
chemical and electromagnetic
What happens to the kinetic energy of the snowball as it rolls across the lawn and gaines mass?
Assuming the lawn is level, the kinetic energy is lost by: 1) Friction 2) The growth of the snowball, as snow sticks to it, its radius increases and this mean that the new snow has to be lifted to the top (from the base) along its direction of role. This converts the kinetic energy into potential energy and slows the snowball.
How are potential and kinetic energy different from each other?
Potential and Kinetic energy relate to position and motion, in that sense Kinetic denotes motion and Potential denotes position. Energy is energy in both cases. There is however a deeper difference between them when it is realized that energy is a quaternion consisting of real or scalar energy and vector energy. Physics consdiers energy a derivative of work and as such is real or scalar as in W=F.D or work =FDcos(x) this is mathematically a scalar. In short physics considers energy a scalar with units joules or newton meter (Nm). However, FxD=FDsin(x) has the same units as energy joule or Nm but it is not called energy it is called Torque and is a vector. This distinction between scalar or real energy and vector energy is significant and is the real distinction between potential and kinetic energy. Kinetic energy is a form of vector energy characterized by Ev= mcV where V is a vector. I use V to distinguish it from v the scalar value of V, v= |V|. Much more could be said but kinetic energy is a form of vector energy.
Describe the energy transformations that occur when a person pushes a bike to the top of a hill and coasts down?
First it's chemical energy from eaten food that turns into heat, a little bit of kinetic energy and potential energy(pushing the bike uphill). Then it's potential energy turning into kinetic energy and a little bit of heat, along with some further chemical energy being used up.(coasting down)

Can an object have kinetic energy and potential energy at the same time?
a body cannot have both kinetic and potential energy at the same time because, a moving body can only possess kinetic energy at a time, but potential energy is one possessed by a body with respect to its possition.
What happens to the kinetic energy of a skateboard that is coasting along a flat surface slows down and coming to a stop?
it change into potential energy beace it slows down
Where on a roller coaster does energy transform?
As it starts to climb the lift hill, the electrical energy builds potential energy. On its way down the first drop, the cars gain kinetic energy (energy of motion) and lose potential energy (stored energy). When it goes up the next hill, the potential energy increases and kinetic decreases, evident in the cars slowing down. Potential is greatest at the top of the highest hill. Along the way, more energy is lost in friction and sound energy.
How does a roller coaster demonstrate potential and kinetic energy in action?
there is a lot of potential energy right before a roller coaster decreases in elevation. potential energy is at its highest on a roller coaster when the roller coaster is at its highest point. when it drops down it uses kinetic energy.
What is usually the highest point on a roller coaster?
The top of the first hill. This is where the coaster has its greatest amount of potential energy which is converted to kinetic energy as it moves along the track.
Changes in energy when a child slides down a slide?
At the top of the slide, the child has a bunch of potential energy. Potential energy becomes converted to kinetic energy as the child accelerates down the slide. At the bottom of the slide, your science teacher will say that all potential energy is converted to kinetic.If your looking to be more technical, some kinetic energy will become heat along the length of the slide via friction. At the end of the slide, the child has to stop right? When the child lands on his feet, or face, the inelastic collision between his feet or face and the sand would produce more heat from kinetic energy. Then he will have neither potential nor kinetic energy, the heat he created would be dissipated into the air, sand, and slide as if everything is back to normal. But he might have some cuts and bruises if he did slide down face first.
Is a marble rolling along at the bottom of a ramp kinetic energy?
Kinetic energy means energy through movement, so yes, it is. Any movement is kinetic energy.
Examples of both kinetic and potential energy?
chemical and electromagnetic
When friction slows an object down where does the lost kinetic energy go?
If you're travelling along a flat road, your potential energy remains constant, so accelerating or braking has no effect on potential energy.
