Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
The unit of work is the Joule (J) Consider a force that acts at an angle. For instance, when a block is being pulled with tension T by a string whose angle of inclination is θ to the horizontal. Tension T. θ. If the block moves a displacement d metres, then: W = ∆E = F d = T cos θ × d .
Physical Science: Tables & Formulas. SI Base Units. SI Derived Units. Prefixes used to designate multiples of a base unit. In general, when converting from base units (m, l, g, etc) or derived units (m2,m3, m/s, Hz, N, J, V, etc) to a multiple greater (kilo, mega, giga, or tera) than the base or derived unit- then divide by the factor.
