Which is the statement of the work energy theorem?
This is a statement of the work–energy theorem, which is expressed mathematically as W = Δ K E = 1 2 m v 2 2 − 1 2 m v 1 2. W = Δ K E = 1 2 m v 2 2 − 1 2 m v 1 2. The subscripts 2 and 1 indicate the final and initial velocity, respectively.
How is the Joule related to work and energy?
The joule (J) is the metric unit of measurement for both work and energy. The measurement of work and energy with the same unit reinforces the idea that work and energy are related and can be converted into one another. 1.0 J = 1.0 N∙m, the units of force multiplied by distance. 1.0 N = 1.0 k∙m/s 2, so 1.0 J = 1.0 k∙m 2 /s 2.
How are power and work related and how are they related?
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. Let’s consider an example that can help illustrate the differences among work, force, and power.
How are work and energy related in physics?
Force is measured in newtons and distance in meters, so joules are equivalent to newton-meters ( N ⋅ m) ( N ⋅ m) Work and energy are closely related. When you do work to move an object, you change the object’s energy. You (or an object) also expend energy to do work. In fact, energy can be defined as the ability to do work.
