they start with the same

he kicked it 10 feet straight up into the air? i think this works.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
