What is the definition of Power?
The rate at which energy is transferred or transformed.
What is the definition of Average Power?
The average rate at which energy is transferred or converted over a time interval.
What is the definition of Instantaneous Power?
The power at a specific moment in time.
Define Work in Physics.
Energy transferred by a force acting over a distance.
What is a Watt?
The SI unit of power, equivalent to one joule per second (1 W = 1 J/s).
How do you calculate power using work and time?
Use the formula: $P = \frac{dW}{dt}$, where P is power, dW is the change in work, and dt is the change in time.
How do you calculate power using force and velocity?
Use the formula: $P = \vec{F} \cdot \vec{v}$, where P is power, F is the force vector, and v is the velocity vector. Remember to use the dot product.
What are the differences between Average Power and Instantaneous Power?
Average Power: Rate of energy transfer over a time interval. | Instantaneous Power: Rate of energy transfer at a specific moment.
Compare calculating power using energy vs. work.
Energy: $P = \frac{\Delta E}{\Delta t}$, focuses on the change in energy. | Work: $P = \frac{W}{\Delta t}$, focuses on the work done during energy transfer.
