1 kw h
= 1 kilowatt hour
= (1000 watts) x (1 hour)

= 3,600,000 watt-seconds
= 3.6 million joules
Velocity is speed in a specific direction and force is a push or pull that may cuase object to stop,move,or change direction they are always forces acting on it. so the different that in force there are always force acting on it
The maximum is 1800 J since energy is not created nor destroyed, it is just transformed. In this example, gravitational potential energy is transformed to kinetic energy.
