    Can a sudden blow truly change potential energy?

    @haruspex So, is it correct to say that mass doesn't have enough time to change its potential energy due to this sudden blow

    Can a sudden blow truly change potential energy?

    Why there will be no change in potential energy due to this sharp blow ? Potential energy is a function of position , so won't this position get changed due to this sharp blow?Please help!

    Finding amplitude of disk and coil spring motion

    Yes , but how do I find angular speed ? .I know angular frequency of the system before and after the putty hits the disc

    Why Won't a Disk Rotate on a Frictionless Bearing?

    yes , I did used parallel axis theorem to find moment of inertia of disk about pivoted point

    Why Won't a Disk Rotate on a Frictionless Bearing?

    I was able to solve first part I.e. time period of the system when bearing has friction I am unable to figure it out why disk will not rotate when it is mounted to frictionless bearing ? I know that due to absence of friction disk cannot rotate but then Mg is also there which can rotate the...
