    B How does an isolated observer know if they're accelerating?

    if your located on the Earth, moving in a horizontal direction and accelerating along this direction then the pendulum will make some angle since the horizontal component of the tension force ( string of the pendulum) will be unbalanced

    B How does an isolated observer know if they're accelerating?

    The easiest way to determine if your accelerating is to make a simple pendulum. IF the pendulum makes some angle with the vertical then your accelerating. In other words your frame of reference is one which is non inertial ( provided there is some deflection.)

    Spring force question with a mass suspended on a spring

    Note here the masss stops only temporarily before moving up. At its lowest point the total energy is the spring energy. At the equilibrium point x = 0.09 m, the net force is zero and the forces balance. Hence the acceleration is zero and the velocity is maximum. ( since as the spring approaches...

    B Lenz's law questions from a dad of a smart son

    Hey this is great thing to do for a project on Lenz's Law. Have a thin loop of copper made into a loop. Connect the loop to one end of a long bar (say 70cm) Next pivot the bar close to its center of mass. Making sure the bar can rotate freely in the horizontal plan and the plan of the loop...

    Hi, yeh I have been a bit lazy for the past few years. I'm hoping to further my knowledge in physics and I,m really looking forward to learning with the rest of you
