One cricket ball and One plastic ball are dropped from the same height. Whichwill reach the ground with(a) more energy(b) less power? |
|
Answer» the potential energy would be converted to kinetic energy. the potential energy is given byP.E.= mghacceleration due to gravity and height is same for both the balls, the one with mom as we have more energy. so the cricket ball will have more energy. the time taken by the balls to reach the ground could be same if a resistance and other factors and neglected. Power= Workdone/ timeas time is same, the ball which has lesser work would have lesser power. plastic ball would have lesser power. |
