Christopher who cares?
Ms. Sue is back boiiiiiiiiiiiiiiiis!
The work-energy theorem states that the work done on an object is equal to the change in its energy. It can be represented as an equation:
W = ΔE
In this equation, W represents the work done on the object, and ΔE represents the change in energy of the object.
To understand how to get this equation, we look at the definitions of work and energy. Work is defined as the force applied to an object multiplied by the distance it is moved in the direction of the force:
W = F * d
Energy, on the other hand, can exist in different forms, such as kinetic energy (energy of motion) and potential energy (energy stored in an object due to its position). The change in energy can then be expressed as the difference between the final energy and the initial energy:
ΔE = E_f - E_i
Combining these definitions, we can equate the work done to the change in energy:
W = ΔE
Therefore, the correct representation of the work-energy theorem as an equation is W = ΔE.
