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.
The anaerobic energy system is important for a goal shooter in netball as it provides quick bursts of energy needed for explosive movements, such as jumping and sprinting to get into scoring position. Training this energy system can help improve speed, power, and agility on the court.
In general, no – energy input is not usually greater than energy output. In a closed system, energy is conserved, meaning that the total amount of energy remains constant. However, in real-world systems, there may be inefficiencies or losses that result in some energy input being converted into forms that are not useful as output.
The greater its kinetic energy.
The one with the greater velocity will have the greater kinetic energy.
The kinetic type does.
Nitrogen typically has a greater bond energy than oxygen. This is because nitrogen forms a triple bond (N≡N) in its diatomic form, which is stronger than the double bond (O=O) found in molecular oxygen.

Potential energy is determined by the mass of an object and its distance from the ground. Therefore, the skydiver with greater mass will have greater potential energy when they are the same distance from the ground.
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.
The three factors that determine the amount of energy required for an activity are body weight, intensity of the activity, and the duration of the activity.
Not necessarily. The mechanical energy of an object depends on both its mass and its velocity. While a larger mass can contribute to greater mechanical energy, a faster-moving object with smaller mass could have greater mechanical energy.
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.
