What is the formula for force ?
Newton's First Law deals with an object with no net force. Newton's Second Law talks about an object that has net force. It states that when the net force acting on an object is not zero, the object will accelerate at the direction of the exerted force. The acceleration is directly proportional to the net force and inversely proportional to the mass. It can be expressed in formula    

    F = ma

where:

    F is the net force in N,
    m is the mass of an object in kg and
    a is its acceleration in m/s2.
