Questions & Answers

Q: What is potential energy and how is it increased?

Potential energy is stored energy that can be increased by applying a force over a distance, storing work in an object.

Q: Can a single object have potential energy?

No, a single object cannot have potential energy, as potential energy is defined by the position of a system of objects relative to a reference point.

Q: How is gravitational potential energy calculated?

Gravitational potential energy is calculated as the mass of an object times the acceleration due to gravity times the change in height or position relative to a reference point.

Q: How is work related to potential energy?

The work done by an applied force on an object is equal to the change in gravitational potential energy, showing the direct relationship between work and potential energy.

Summary & Key Takeaways

• Potential energy is stored energy that can be increased by applying a force over a distance.

• Gravitational potential energy is the energy of position relative to a reference point.

• The work done by an applied force is equal to the change in potential energy.
