Work, Energy, and Power: Crash Course Physics #9
CrashCourse・2 minutes read
Work in physics is the application of force over a distance, measured in Joules and calculated as force times distance times the cosine of the angle. Energy and work are closely related, with work representing a change in energy when an external force is applied, while power is defined as work over time measured in Watts.
Insights
- Work in physics involves applying a force over a distance, with the amount of work done calculated by multiplying the force by the distance. This relationship is fundamental in understanding how energy is transferred and transformed in physical systems.
- Energy and work are intricately linked concepts, where work represents a change in energy due to external forces. Different forms of energy, such as kinetic and potential energy, play crucial roles in determining how work is done and how systems behave in response to forces applied.
