Newton's 2 nd law observations from experiment: more force → greater acceleration more mass → lesser acceleration acceleration is in the direction of the net force Net force vector sum! follow up: Workbook exercises 4.9-11, page 4-3 a = F net m = 1 m i F i

Newton's 1 st law Is a force needed to produce uniform motion? no acceleration could mean no velocity (static equilibrium) OR constant velocity (uniform motion) follow up: workbook exercise 4.20, page 4-5 i F = 0 a = 0
