Forces & Newton's 1st Law

Newton’s 1st law Objectives:

N1.1  

N1.2  draw a properly labeled free body diagram showing all forces acting on an object including magnitude and direction

N1.3   tell whether the forces are balanced or unbalanced for an object based on its motion

N1.4   Calculate net force for different situations

N1.5   use Newton’s 1st law to quantitatively determine the forces acting on an object moving at a constant velocity

N1.6   recognize/apply Newton’s 1st law to different situations and relate it to the terms equilibrium and inertia

N1.7   identify and apply standard contact forces to a free body diagram:  weight, normal, friction, applied, tension

N1.8
