Length is a characterization of spatial dimension, i.e. distance. It is a completely different physical concept from energy.

Which is not a factor in either kinetic or potential energy?
length
How does the length affect the kinetic energy?
Yes, the length affects the amount of kinetic energy. The shorter the length the more kinetic energy.
Where is the potential energy in a pendulum?
A pendulum swings back and forth with a period based on its length. When it is pointing directly down, moving horizontally with maximum speed, there is no potential energy; all the energy is kinetic. When it is maximally away from this position it has stopped and so has no kinetic energy; all the energy is potential. Thus at any one time there is the same amount of energy in a swinging pendulum but depending on where it is in its arc of motion there will be different amounts of kinetic and potential energy.
What are two types of mechanical energy?
The traditional definitions are kinetic energy (due to motion) and potential energy (due to the relative location within a gravity field).There is really only one type and it is the sum of the gravitational potential energy and the kinetic energy. Mechanical energy = (Mass)((Gravitational acceleration)(Height)+(1/2)(Velocity)²)
What is the relationship between the length of a ramp and the speed at the bottom?
The Object moving down the Ramp will have its POTENTIAL Energy (Speed=0) at the top of the Ramp changed to Kinetic Energy as it travels DOWN the Ramp. For any given INCLINE the LENGTH of the Ramp will dictate its HEIGHT. The higher the top of the ramp, the greater the Potential Energy to be Converted into Kinetic Energy. The Formula for K.E. is : K.E. = 1/2 Mass x Velocity2 (the 2 means Squared) So as the Potential Energy increases so does the Kinetic Energy. while the Mass is a Constant. Therefore the Velocity MUST increase as well to balance the K.E. equation.
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.
Does a joule measure potential energy or kinetic energy?
Both a joule is a measurement unit of energy. Like centimeters measures both length and width joules are aunit to measure any type of energy
Can you give me an example of a potential energy?
Potential energy is energy of an object due to its location or the effect of forces which are "locked" in place. One example is a book on a shelf: it has gravitational potential energy which is realised when it falls. Another is a stretched spring whose potential energy is realised when the spring is allowed to return to its normal length.
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.
What is an example of gravitational potential energy into kinetic energy?
-- pouring beer out of a bottle into a glass-- sledding or skiing down a snow-covered hillside-- plopping effervescent antacid tablets into a glass of water-- coasting down a hill on your bicycle-- everything a roller coaster does after it passes the top of the first hill-- rolling your car down the hill to the filling station after running out of gasAn object in free fall - if it is falling down, its potential energy decreases, its kinetic energy increases.
Compressed springs are what kind of energy?
The potential energy of a spring is defined by this equation: U=.5kx2 U= potential energy (in joules) k= the spring constant x= the displacement of the spring from equilibrium. (the amount that the spring is stretched or compressed) This equation tells us that as a spring is compressed by a distance x, the potential energy increases proportionately to x2
What do heat temperature and thermal energy all have in common?
-Thermal energy and mechanical energy are the sum of potential and kinetic energy.-They can change to another form of energy.-They can't be created or destroyed due to the law of conservation of energy.
