ā 11y agoIf you push with one newton of force and keep it up through a distance of one meter,
then you've expended one joule of energy. It doesn't matter what you're pushing, or
what its mass is.

Technically, once you know the weight of the box and the height of the platform, you can state the amount of"work" or "energy" needed to raise the box onto the platform. But there's no such thing as the power "needed"to do the job.Power is just the rate of doing work. You can calculate the amount of work needed, but it doesn't matter whetherthe work is done slowly or fast ... with low or high power.
Amount needed: 7 times 6p = 42p

Technically, no. However, in this context, yes. It wouldn't actually save energy, but it can lower the amount if energy needed to do a task. For example, if you insulate your house well, you would not need to heat/cool is as aggressively because the hot/cold air would not pass through the walls to the outside air nearly as easily as a house that has no or poor insulation.
The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.
Yes, the amount of energy that food contains is measured in calories. When we refer to calories in the context of food, we are actually referring to kilocalories (kcal), which represent the amount of energy needed to raise the temperature of 1 kilogram of water by 1 degree Celsius.
Specific heat is the amount of heat needed to melt one kilogram of a substance...heat of fusion
Yes, one calorie is the amount of heat needed to raise the temperature of 1 kilogram of water 1 degree Celsius.
The amount of heat needed to increase the temperature of a 1-kilogram substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by one degree Celsius.
The amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius is 4186 Joules, which is the specific heat capacity of water.
The definition of a calorie has to do with the specific haet of water. The gram calorie (abbreviated "cal") is the amount of energy needed to heat one gram of water by one degree celsius (centigrade). The kilogram calorie (abbreviated "C") is the amount of energy needed to heat one kilogram of water by one degree celsius. Thus one C equals one kcal or "kilo calorie" often found on food packs enegry declaration and such. One cal equals about 4.2 Joules which is the scientific standar unit for energy.
The amount of energy needed to raise the temperature of 1 kg of a substance by 1 degree Celsius is known as the specific heat capacity of the substance. It varies depending on the substance and is typically measured in joules per kilogram per degree Celsius (J/kgĀ°C).
The amount of energy needed to move an electron from one energy level to another is known as the energy difference between the two levels. This energy difference is typically quantified in electron volts (eV) or joules.
Activation energy
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
It is a calorie
