The amount of work done by a machine is determined by the energy input required to operate it efficiently. Machines with higher efficiency require less energy to produce the same amount of work. Therefore, the relationship between work and energy needed is directly related - the more efficient the machine, the less energy required to perform a given amount of work.

Does a machine's mechanical advantage reduce or increase effort?
A machine's mechanical advantage increases the force output compared to the input force required. This means that the machine helps to reduce the amount of effort needed to perform a task.
What most influences the amount of energy needed to change the temperature of a substance?
The amount of energy needed to change the temperature of a substance is most influenced by its specific heat capacity, which is the amount of energy required to raise the temperature of a given mass of the substance by 1 degree Celsius. Substances with higher specific heat capacities require more energy to change temperature compared to those with lower specific heat capacities. Additionally, the mass of the substance being heated also plays a role in determining the amount of energy needed.
How does friction impact the amount of mechanical energy produced by a machine?
Well friction is the opposing force to any object who is doing work against another. So the force needed to overcome friction costs more energy than required thus decreasing efficiency of the machine.
How is energy needed to make machine work?
Energy is needed to make machines work because it powers the movement and function of the various components within the machine. This energy can come from sources such as electricity, fuel, or human input, and is converted into the mechanical energy needed to operate the machine. Without energy, machines would not be able to function and perform their intended tasks.
What is the energy conversion for a pepper grinding machine?
A pepper grinding machine converts electrical energy into mechanical energy to grind the peppercorns. The electric motor in the machine provides the mechanical energy needed to rotate the grinder and crush the peppercorns into smaller pieces.
How does every simple machine make work easier?
By reducing the amount of energy needed to preform an action

What is chloroplast compared to?
Chloroplast is compared to a power house. Its compared to that because it provide the energy needed to function.

Why is the amount of work that comes out a little less than the force needed to make a machine work?
Because some of the energy (work) is converted to heat as the parts of the machine rub against each other.

It refers to the amount of energy needed to start the reaction?
Activation energy
The amount of energy needed to move an electron from one energy level to another is an?
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.
What form of energy is needed making a sewing machine work?
kiran ben
How do enzymes effect the energy profile?
It lowers the amount of activation energy needed
Is a measure of the amount of water vapor that air is holding compared to the amount needed for saturated at a specific temperature?
The amount of water actually contained in air compared to the amount it could contain is known as relative humidity.
