  • How to calculate pendulum hammer impact force : AskEngineers

    M_hammer*g* sin (theta) = E = 1/2 * m * v 2 and solve for velocity. The velocity at impact is the same as the velocity at theta = 0. Force is probably the wrong thing to be calculating, because the hammer stops almost instantaneously. Impulse and energy make more sense with that kind of collision. You're right.

  • Pendulum Impact Force Calculation | Physics Forums

    Force is bad choice here, because the force depend on the time the impact takes (which can be very short indeed). You'd be much better off with momentum; you would want to calculate the momentum of the pendulum, right before the impact, and then apply conservation of momentum, which does give you the subsequent motion of the impacted object (under suitable constraints).

  • Simple Pendulum: Theory, Diagram, and Formula.

    The restoring force of the pendulum from the above is, F = -mgL θ. This force is responsible for restoring the pendulum to its equilibrium position. However, due to the inertia of motion, the pendulum passes the equilibrium position and swings to the other side. This motion is periodic and can be solved using differential equation analysis.
