Question

In the experiment to measure the coefficient of kinetic friction by sliding a block down on inclined plane, it is required that the block move at constant velocity. Why is this requirement necessary? 5. Frictional forces on a block on an inclined plane are directed down the plane (TRUE/FALSE).

Answer 1

akk vt myning h mypinou ng mgcano In measuring up, constant velocity is necessary, so that met turco on block is Z ero when not fares or not aucturation . in Zero, then . . 1. mgrino - brezo when constant velicity, then we can easily aquate the frictional faree with (mgaine) and this can calculate the frictional force. fk = mpsine umglaro = mpnino un = tano s) If the block is sliding downwards with constant velocity, then prictional force is upwards. False - 9 wefficient of kinetic friction doesnot directly depend on velocity of object But when object moves with contant Velocity theu le= tamo where o in o in augle of inclination augle of of ramp'
