What is the work-kinetic energy theorem?? Give an example.

the net work done by all the forces acting on an object is equal to the change in the object’s kinetic energy. Trick question there is no example because this has never been proven in nature.

The net work done by all the forces acting on an object is equal to the change in the object’s kinetic energy. The more force you put on an object the faster it goes. Like the faster you peddle your bike and the steeper the hiller the faster your bike will go.

This theorem allows us to think if kinetic energy as the work that an object can do while changes speed or as the amount of energy stored in the motion of an object. One exaplem of it is when a frozen pond, a person kicks a 10 kg sled, giving it an initial speed of 2.2 m/s. How far does the sled move if the coefficient of knitic friction between the sld and the ice is 0.10? It's going to be the work-kinetic energy.

The work kinetic energy theorem states that the net work done by all the forces acting on an object is equal to the change in the object’s kinetic energy. An example would be on a frozen pond, a pwerson kicks a 10 kg sled, giving it an initial speed of 2.2 m/s. How far does the sled move if the coefficient of kinetic friction between the sled and the ice is 0.10? D equals 2.5 m.

The net work done by all the forces acting on an object is equal to the change. It is a pretty intersting thing. It is fun.

Work-kinetic energy theorem states that net work equals the change in kinetic energy. The equation is Wnet=(change)KE. An example is a car decelerating has net work of the change in its kinetic energy.

The work work-kinetic energy theorem states that net work equals the change in kinetic energy. The equation is Wnet=(change)KE. The more force or less force you put on an object, the faster or slower it goes. Different things change it. Yea.
