    Undergrad Faraday's Law Equation: Derivative vs Delta

    My textbook gives the equation for Faraday's Law as ε=-(dΦB)/(dt) , the derivative of magnetic flux with respect to time. I have also seen Faraday's law expressed as ε= -(ΔΦB)/(Δt). Are these two forms equivalent? Thanks!

    Conservation of Energy in Trampoline Bounce

    I was able to calculate the correct answer (given by a solution sheet), V=5.364 m/s, using the momentum impulse equation, P0+J=Pf. If this value is correct, however, I don't understand how energy is being conserved. The speed increases after the person bounces off the trampoline while the mass...
