Work Energy Theorem Worksheet Answer Key - The subscripts 2 and 1 indicate the final and initial velocity, respectively. The work done by a nonconservative force can be expressed w nc = (δke) + (δpe) fact: They apply a cumulative force of 1080 n to push the car 218 m to the nearest fuel station. These calculations allow us to find the final kinetic energy, 1 2 mv 2 1 2 mv 2, and thus the final speed v v.

The Work Energy Theorem Worksheet

According to this theorem, the net work done on a body is equal to the change in kinetic energy of the body. A jack used to raise a car b. The work done on an object by a net force equals the change in kinetic energy of the object:

What Net Force Needs To Be Applied If A.
