Newton’s 2 nd  Law of Motion!
2 nd  Law This law describes  changes  in the motion of objects That change is acceleration ( Δ v/t).  The cause of acceleration is force Acceleration depends on NET force NET force & acceleration are  proportional .
2 nd  Law Mass is  inversely proportional  to acceleration. As the mass increases, the acceleration decreases.
2 nd  Law Putting these together gives us Newton’s 2 nd  Law of Motion The acceleration of an object is directly proportional to the net force and inversely proportional to the mass
2 nd  Law acceleration =  net force   mass
2 nd  Law Can change the formula around to. . . F = ma
Mass vs. Weight Mass  – the measure of the  amount  of material (matter) in an object. Weight  – a measure of the  gravitational  force acting on the object
Mass remains the same – no matter the location Weight is dependent on gravity Mass & weight are proportional to each other, but not equal W = mg Acceleration due to gravity is 9.8m/s 2 .
