Detailed explanation-1: -Power in its simplest form is the product of force multiplied by distance, divided by time. In a sporting context, force can be substituted for strength, and time/distance indicated by the speed of movement.
Detailed explanation-2: -Hence, the relationship between power, force, and velocity is P = F x v .
Detailed explanation-3: -Calculating Power Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v. More power is seen when the system is both strong in force and fast in velocity.
Detailed explanation-4: -In physics, power is defined as the rate at which work is done. In other words, it measures how quickly energy is being transferred or transformed.
Detailed explanation-5: -Power is defined as the rate of doing work concerning time or energy utilized per unit of time. P = E t, P=Power, E=Energy, t=time. The S.I unit of power is Watt ( ). The relation between power, force, and velocity is given by P = F × v where, F= force and v= velocity.
