How to solve for instantaneous power
WebRate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours. Created by Sal Khan. Sort by: Top Voted Questions Tips & Thanks WebFirstly, instantaneous power is equal to F · v. If we said that F = m · a, and plug that into the instantaneous power, then we would have P = m · a · v.

WebMar 26, 2016 · In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object’s speed, v, is just s divided by t, so the equation breaks down to.
