Identify the energy transformation in the following;-
i) hydroelectric power
ii) explosion of cracker
iii) oscillating pendulum

1 ) the kinetic energy of flowing water gets transfered into electrical electricity
2)the chemical energy that causes the cracker to explode transfers into heat and light
3)the kinetic energy gets transfered into potential energy and back to kinetic energy this process keeps on going on till the pendulum comes to rest .
