Work-Energy Theorem: Definition and Application

1. Work-Energy Theorem: Definition and Application

The work-energy theorem relates the net work done of forces on an object and the change in the kinetic energy of the object. Learn about the definition and application of the work-energy theorem, explore work as a change in energy, discover how the work-energy theorem can be applied to the potential energy of an object, and understand how the increase or decrease in energy is associated with the work-energy theorem.

Conservation of Mechanical Energy

2. Conservation of Mechanical Energy

In physics, mechanical energy refers to the power that an object obtains based on its position or movement. Learn about the conservation of mechanical energy, including kinetic and potential mechanical energy. Explore how energy is conserved in a system, review conservation in action, and recognize outside forces on the system.

Angular Momentum vs. Linear Momentum

3. Angular Momentum vs. Linear Momentum

Angular momentum is used to describe a rotating motion while linear momentum is concerned with translating motion. Learn more about the definitions of angular and linear momentum, and also the two different equations used to calculate angular momentum.

Conservation of Linear Momentum: Formula and Examples

4. Conservation of Linear Momentum: Formula and Examples

Conservation of linear momentum explains that the momentum of a system will remain the same unless an outside force is applied. Using examples, learn the formula comprising Newton's third law of motion, the relationship between momentum and external forces, and how momentum is conserved in a system.

Conservation of Angular Momentum

5. Conservation of Angular Momentum

The law of conservation of angular momentum states that there will be no change in the total angular momentum if no external torque act on the system. Explore the angular momentum of an object in orbit and review an example calculation.
