Efficiency cannot be greater than 100% because efficiency measures energy, and since energy is not made, only transfered (conservation of energy) then we cannot gain energy. Hence the energy out must be at most the energy in. Thus efficiency can be at most 100%
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
No, due to the fact machines loose energy due to heat/thermal energy. you will always loose some amount of energy.
The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied. In this case it would be 300N x 10m to get 3000J. This energy is transferred in 10 seconds and since power is energy transferred per unit time... 3000J divided by 10 seconds equals 300 Watts or 300 Joules per second.
The amount of work done by each person can be calculated by analyzing the amount of energy they each use to climb the stairs. Energy is related to work (force multiplied by distance) and can be measured in joules. The person who climbs the stairs in 30 seconds will have used more energy (and thus done more work) than the person who climbs the stairs in 40 seconds. This is because the person who climbs in 30 seconds had to exert more force to climb the stairs faster thus expending more energy in a shorter amount of time.The following factors will determine how much work each person did: The weight of each person The amount of stairs climbed The rate of ascent (how fast they climbed the stairs) The amount of energy usedAlthough the two people weigh the same the person who climbed the stairs in 30 seconds used more energy than the person who climbed in 40 seconds. This is because the person who climbed in 30 seconds had to exert more force in order to ascend the stairs faster. This force requires more energy to be used and thus the person who climbed in 30 seconds did more work.
Goal Shooter predominately uses the ATP-PC system as it uses short but fast amounts of energy at a time, lasting for up to 10 seconds.
A wave transports energy. The greater the energy, the greater the amplitude of the wave.
The energy input is always greater than energy output.
The one with the greater velocity will have the greater kinetic energy.
The kinetic type does.
Oxygen has the greater bond energy.
potassium is greater in the second ionization energy.
potential energy.
The meaning of energy in scientific terms: The ability to do work; as the Greek meaning goes: "Activity".
Under normal circumstances, energy can't be created or destroyed. But in any activity (and energy is required for any activity), part of the useful energy is converted into unusable energy - for example, waste heat.
Not really. Any activity requires energy. Some a lot, some just a small amount.
It isn't so. Potential energy can be greater, or less, for a given object, depending on its position and its speed.
