The way that I remembered (and still do) Newton's Laws of Motion.
The first law - Inertia = I made up a hyphenated word "One - ertia"
The Third Law - equal and opposite = a sideways 3 - turn the three so the
openings of the three are upward - each side of the sideways three is
"equal and opposite"
Once I know which the 1st and third are - the second is the only one left.
acceleration is directly related to the force applied If I push down the
gas pedal in 2nd gear - I accelerate in direct proportion to the force on
the gas pedal.
