What work has been done by the force of gravity, which acts on the falling apple, if the potential energy of the apple has decreased from 4 J to zero?
The work of gravity can be calculated using the formula:
A = Ft * h = En1 – En2, where En1 is the potential energy that characterizes the initial position of the apple (En1 = 4 J), En1 is the potential energy that characterizes the final position of the apple (En2 = 0 J).
Let’s calculate the work of gravity:
A = En1 – En2 = 4 – 0 = 4 J.
Answer: The force of gravity performs work equal to 4 J.
