If we know the magnitude and direction of the net force on an object of known mass, Newton's second law of motion lets us find its acceleration.
Newton's second law of motion states that the acceleration (a) of an object is directly proportional to the net force (F) acting on it and inversely proportional to its mass (m):
a = F / m
Therefore, if we know the net force and the mass of the object, we can use Newton's second law to find its acceleration. The direction of the acceleration will be in the same direction as the net force acting on the object.
