Remember the Units!!!

Yes, remembering the unit is not always fun for kids doing first year of Physics.

I think this one is neat trick:
Newton walks a meter and becomes Joule; Joule sits on time and becomes Watt

Newton walks a meter and becomes Joule; Joule sits on time and becomes Watt

Formula:
Work = Force*distance (Joule)
Power = Work/time (Watt)
