Newton's Second Law The acceleration (a) of a body is parallel and directly proportional to the net force (F) and inversely proportional to the mass (m), i.e., F = ma. Mass is measured in kilograms (kg) Acceleration is measured in meters per second squared (m/s²) Force is measured in Newtons (N) which is equivalent to (kg) x (m) / (s)^2 This unit is easily obtained from the equation by simply plugging in the units rather than numbers. F = ma = [kg] x [m/s²] = (kg) x (m) / (s² ) = N Newton's Laws of Motion: First law: The velocity of a body remains constant unless the body is acted upon by an external force. Second law: The acceleration (a) of a body is parallel and directly proportional to the net force (F) and inversely proportional to the mass (m), i.e., F = ma. Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear.
