Force and Acceleration
... According to this law, the force acting on an object is given by Force α M x a Here M is the mass of the object and a is the acceleration. The proportionality symbol “α” tells that Force = k.M.a Where k is a constant. The unit of mass is gram or kilogram. The units of acceleration are cm/s2 or m/s2. ...
