Lab Report - Activity P08: Newton`s Second Law – Constant Force
... The acceleration of an object is directly proportional to and in the same direction as the net force, and inversely proportional to the mass of the object: F a net m a is acceleration, Fnet is net force, and m is mass. Applying Newton’s Second Law to the static setup used in this activity for an o ...
