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.

How do you calculate Average Power using energy?

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: $P_{avg} = \frac{\Delta E}{\Delta t}$ .

How do you calculate Average Power using work?

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

How do you calculate Instantaneous Power?

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: $P_{inst} = Fv \cos \theta$ .
