WebFeb 20, 2024 · The SI unit for power is the watt \ (W\), where 1 watt equals 1 joule/second \ ( (1 \, W = 1 \, J/s)\). Because work is energy transfer, power is also the rate at which energy is expended. A 60-W light bulb, for example, expends 60 J of energy per second. Great power means a large amount of work or energy developed in a short time. WebOct 28, 2024 · The next step is to calculate the power according to the work-time equation for power, which is P = W /t P = W / t Therefore, the power is P = 21J /9s P = 21 J / 9 s …
WebThe force exerted back by the spring is known as Hooke's law. \vec F_s= -k \vec x F s = −kx. Where F_s F s is the force exerted by the spring, x x is the displacement relative to the unstretched length of the spring, and k k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always ... WebFrom Work and Kinetic Energy, the instantaneous power (or just power) is defined as the rate of doing work, P = dW dt. If we have a constant net torque, Figure becomes W = τθ and the power is P = dW dt = d dt(τθ) = …
