an object of mass 25 kg is raised to a height of 6 m above the ground. what is the potential energy? if the object is allowed to fall find its kinetic energy when it is halfway down |
|
Answer» Potential energy of object when at a height of 6 m : P.E. = m×g×h P.E. = 25×9.8×6 P.E. = 1470 J Kinetic Energy when the object is halfway down will be 735 Joules because the Potential Energy will be reduced to half and turned to Kinetic Energy at that time. |
