... Summary of Newton’s Three Laws • An object tends to remain at rest, or, if moving, to continue moving at constant speed in a straight line (1st Law). Objects tend to resist changes in motion (inertia) – mass measures this. • (2nd Law) When there is a net force on an object, it will accelerate: a = ...
