Question
CH 6 Work Introduction to Potential Energy Constants Learning Goal: Understand that conservative forces can be removed from the work integral by incorporating them into a new form of energy called potential energy that must be added to the kinetic energ to get the total mechanical energy The first part of this problem contains short-answer questions that review the work-energy theorem. In the second part we introduce the concept of potential energy. But for now, please answer in terms of the work-energy theorem.Explanation / Answer
A. The correct option is distance / kinetic.
When an external force acting on a particle as it moves over a distance changes the kinetic energy of the particle. The work done by the force will increase the kinetic energy.
B. The correct option is Position.
The product of force and change in position is the work done by the external force. This provide the change in kinetic energy.
C. The correct option is force / kinetic.
The work is done by the gravitational force which will increase the kinetic energy.
D. The correct opion is change / potential.
Increased Kinetic energy will come from the reduction in potential energy.
E. The correct option is sum / conserved.
The total mechanical energy (sum of kinetic and potential) energy is same for gravitational forces.
