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 inter relation among work energy and power?
Answer: Work, energy and power are inter-related and interdependent. ... Power- It is the effectiveness of doing work . It is the rate of doing work. Energy- It is the capacity or potential to work.
What is the relationship between work-energy and power?
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.
Is power same as energy?
If we get even more technical, energy is the capacity of doing work and power is the time rate of doing work (or delivering energy, according to Encyclopedia Britannica). To get the same job done repetitively would require the same amount of energy , but you can apply more power if you want to get it done faster.
What are two types energy?
- Potential energy.
- Kinetic energy.
What is the relationship between time and power?
Power and time are inversely proportional .
How do you calculate energy from power?
Formula for calculating power from electrical energy
The formula that links energy and power is: Energy = Power x Time . The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.
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 power used for?
Power is one of the key units in many electronic circuits. It can be used to indicate the level of heat dissipated in a unit or even an individual component, it can be used to define the power consumed, and it can also be used to define the amount of power generated by the system to pass on to the next item.
How do you find energy with power and time?
Power can be expressed as P = Work/Change in Time , instead of P = Change in Energy/Change in Time, because the change in energy is basically the work done.
Is kinetic energy the same as power?
Different Forms of Power and Energy
These include kinetic, potential, thermal, gravitational, electromagnetic, sound, light and elastic. ... For instance potential energy is dependent on the position of the object, whereas kinetic energy is the energy required to accelerate an object to a particular speed , and so on.
What is the highest form of energy?
From the highest energy to lowest are: gamma rays , x-rays, ultraviolet (UV), visible, infrared, microwave, and radio.
What are the 4 types of energy do humans have?
Kinetic, potential, and chemical energy .
What are the 5 sources of energy?
- Solar Energy. The primary source of energy is the sun. ...
- Wind Energy. Wind power is becoming more and more common. ...
- Geothermal Energy. Source: Canva. ...
- Hydrogen Energy. ...
- Tidal Energy. ...
- Wave Energy. ...
- Hydroelectric Energy. ...
- Biomass Energy.
What is the difference between power and current?
Power is the product of voltage and current and is the work done in moving a quantity of charge through a resistance.
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).
