Work is referred to as the process of energy that is transferred to an object’s motion by applying force. It is generally represented as the product of displacement and force. Power is the amount of energy that is transferred in a unit of time. The formula for calculating the force is Work = Force * Displacement.
What is the relation among work power and time?
Power = work done/time .
What is the relationship between work power and time?
The point is that for the same amount of work, power and time are inversely proportional . The power equation suggests that a more powerful engine can do the same amount of work in less time. A person is also a machine that has a power rating.
What are the 3 equations for power?
P = ΔV 2 / R
We now have three equations for electrical power, with two derived from the first using the Ohm’s law equation. These equations are often used in problems involving the computation of power from known values of electric potential difference (ΔV), current (I), and resistance (R).
What are the significant similarities and differences between work and power?
The main relationship or difference between the two is time . Work is the amount of energy necessary to move an object from one point to another. Imagine moving a table or seat from your living room to your dining room. On the other hand, power is the rate at which the energy is spent.
What is difference work and power?
Work is defined as the process of energy transfer to the motion of an object through the application of force. ... Power is defined as the amount of energy transferred in unit time.
What is the relation between energy and power?
Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred . It is not energy but is often confused with energy.
What is the relation between work?
The energy transferred by force to move any object is known as work or work done. Therefore, work and energy have a direct relationship . The difference in the kinetic energy of an object is called work done by the object. Work and energy are common terms in Physics and can be considered two sides of a coin.
How do you find minimum power?
Use the formula for power: Power = Voltage x Current, or P = VI. If you are trying to calculate the minimum load and you happen to only know the power and voltage ratings of your power supply, you can use the formula P = V 2 /R , which can become R = V 2 /P.
What is current formula?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R . The SI unit of current is Ampere (Amp).
What do work and power have in common?
2 Answers. Work is the energy needed to apply a force to move an object a particular distance , where force is parallel to the displacement. Power is the rate at which that work is done.
What is the relationship between work and power quizlet?
Work is how much force it takes to move an object in the same direction as the force. Power is how long it takes you to do the work .
What is difference between energy and power?
What is the Difference Between Energy and Power? Energy is an object’s ability to complete work . Power refers to the rate at which an object can complete work. Energy’s SI Unit is Joules.
What is an example of power?
Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles . An example of power is the authority a local government has to collect taxes. ... The definition of power is operating electrically or having strength or force.
What are the factors that affect your power?
- Weather. Weather can be unpredictable, but that doesn’t mean your power bill has to be! ...
- The Number of People in Your Home. ...
- Your Home’s Characteristics. ...
- Electrical Appliances and Devices.
