Equation linking power mass and speed
WebMar 16, 2024 · The kinetic energy equation is as follows: KE = 0.5 × m × v², where: m – Mass; and v – Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object. The same … WebThe expression P = F v expresses a relation between the instantaneous power, the force and the velocity. You don't have to average for it to be true. In your case, the velocity in constant. This implies that the net force is zero. Hence, the force propelling the car is equal and opposite to the friction force.
