On a typical Saturday, Jimmy decided to go to the park with his brother Bob.
When we turn on the lights, the electricity from the wires flows and turns the light on
We have a similar case here, electricity runs through the wire and lights the pixels
Jimmy and Bob get on the car to go to the park
Cars turn the chemical potential energy, or gas, into thermal kinetic, and into mechanical energy, which is how cars move!
Jimmy and Bob have arrived at the park.
Oops, I dropped my keys
Yes, the keys start with gravitational potential energy, change to kinetic mechanical energy, and finally changes to elastic potential energy when it hits the ground. What results is thermal and sound.
They have arrived at the park. They realize that the light energy from the sun transfers the light energy into the plants, which store it as chemical potential energy.
The mechanical energy from your leg transfers into elastic potential energy when it hits the ball, and the ball then has mechanical kinetic energy.
Jimmy and Bob have arrived at the picnic. Jimmy tells Bob that the burning fire is a result of the chemical potential energy changing into heat.
When I eat this marshmallow, the kinetic energy from my chewing turns into chemical potential energy
