magnitudes of all the forces. Each force must be represented by a distinct arrow starting on and pointing away from the dot. Quantitative Analysis RTE Blake is asked to use Newton's second law to derive an equation that relates the force of gravity and the normal force from the surface exerted on the block. Annotate his derivation by filling in the right side of the table below. For each line of the derivation, explain in words what was done mathematically. The first line is done for you as an example. EF We start with Newton's second law, which says that the sum of all the forces exerted on an object is equal to the object's mass times the object's acceleration. F -F
