What is the relationship between work and power?
The relationship between work and power is that power is how fast work is performed. Mechanical power is equal to how fast work is performed over time and can be represented by the equation P=W/t, where P is equal to power, W is equal to work and t is equal to time.
Do power and work have direct relationships?
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 are the similarities between power and work?
Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W) which equals 1 joule of work per second (J/s).
How do the units of work and power compare quizlet?
How do the units of work and power compare? The unit for work is a watt. The unit for power is a joule, which is a watt-second. The unit for work is a watt.
What is work and power?
Work is defined as the process of energy transfer to the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule. Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt.
What is the importance of power in doing work?
The equation for power connects work done and time. Since we know that work is done by forces, and forces can move objects, we might expect that knowing the power can allow us to learn something about the motion of a body over time. This can be a particularly useful result.
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 the similarity between power and energy?
With power and energy, power is units of energy divided by time. The same difference as distance and velocity. The units of power are watts, the units of energy are joules. A watt is one joule divided by one second.
How do the unit of work and power compare?
How do the units of work and power compare? The unit for work is a watt. The unit for power is a joule, which is a watt-second.
Which statement about work and power describes Hiros actions?
Which statement about work and power describes Hiro's actions? He had more power running than walking. You just studied 47 terms!
What is the relation between work force and displacement?
While force and displacement are inversely propotional. The equation showing the relationship is W=Fd.
What is the differences between work and energy?
Work is the ability to supply force and a change in distance to an object. Energy is the ability to supply or create work.
What is the difference between power and energy?
Energy is the capacity to do some physical activities or work, such as running, jumping, etc., while power is defined as the rate at which the energy is transferred, or the work is completed. The unit used to measure energy is joules, ergs and calories. Power is measured in watts.
