Принцип работы и кинетической энергии
If net force works on an object, the object experiences acceleration (the object experiences displacement). When the object experiences acceleration, the speed of the object changes. In other words, the work done by the net force is related to the object’s initial and final speed.
The work done on an object by constant net force is:
Wсеть = ΣF s
Newton’s second law states that if there is a net force working on an object, the object experiences acceleration.
