The rate at which energy is transferred or transformed.

The average rate at which energy is transferred or converted over a time interval.

The power at a specific moment in time.

Energy transferred by a force acting over a distance.

The SI unit of power, equivalent to one joule per second (1 W = 1 J/s).

Use the formula: $P = \frac{dW}{dt}$, where P is power, dW is the change in work, and dt is the change in time.

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.

1. Determine the change in energy ($\Delta E$). 2. Determine the change in time ($\Delta t$). 3. Divide the change in energy by the change in time: $P_{avg} = \frac{\Delta E}{\Delta t}$.

1. Determine the work done (W). 2. Determine the change in time ($\Delta t$). 3. Divide the work done by the change in time: $P_{avg} = \frac{W}{\Delta t}$.

1. Determine the force (F) acting on the object. 2. Determine the velocity (v) of the object at that instant. 3. Determine the angle ($\theta$) between the force and velocity vectors. 4. Calculate: $P_{inst} = Fv \cos \theta$.
