What are three differences between work and power?
| Work | Power |
|---|---|
| 1. Work done by a force is equal to the product of force and the displacement in the direction of force. | 1. Power of a source is the raw of doing work by it. |
| 2. Work done does not depend on time. | 2. Power spent depends on the time in which work is done. |

What is the relation between work and power?
Power is the rate at which work is done. In this case, rate means per unit of time. Power is calculated by dividing the work done by the time it took to do the work. P = W t P = W t.

What is the difference 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 are two differences between work and energy?
Work is the transferring of an amount of energy with the help of a force covering a particular distance in a direction. Energy is also referred to as the force that works at a certain distance. Both of these can be termed scalar units. For work to occur, there must be a force and movement from one place to another.

What is the difference between and power?
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.

What is the relationship between work and power quizlet?
Power and work are directly related. As the amount of power increases, the amount of work able to be done also increases. A machine with greater power could do more work than a machine with less power in the same amount of time. The unit used to express power is watts.

What is the relationship between work and power and how are they calculated?
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). Power may be measured in a unit called the horsepower. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power.

Are work and power inversely related?
The SI unit of power is the watt (W), which indicates the rate of 1joule of work per 1 second. Power is then directly proportional to the work done and inversely proportional to the time to do the work. Remembering that work is force times displacement (W = F*d), you can derive a corollary for the power equation.
