2 Mechanical translation Newton’s Laws Every body persists in a state of uniform motion, except insofar as it may be compelled by force to change that state. The time rate of change of momentum is equal to the force producing it. To every action there is an equal and opposite reaction. (Principia Philosophiae, 1686, Isaac Newton)
3 Quantities and SI Units “F-L-T” system Define F: force ( Newton [N]) Define L: length ( meter [m]) Define T: time ( second [s]) Derive v: velocity, m: mass “M-L-T” system Define M: mass ( kilogram [kg]) Define L: length ( meter [m]) Define T: time ( second [s]) Derive v: velocity, F: force
