The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object states Newton’s second law of motion. This law pertains to objects with existing forces are unbalanced and how the velocity of an object changes when pushed or pulled. The object will undergo acceleration in the direction you push it. Newton’s second law also states, acceleration is dependent upon two variables. It therefore, depends directly on the net force and inversely on the mass the object has. An increased force is followed by an increases acceleration. While, an increase of mass leads to a decrease of acceleration. So, when there is more force the faster an object will go.

The formula- A=Fnet/m or Fnet=m(a), is used to find the Fnet by multiplying the acceleration and mass or to find the acceleration by divided the Fnet by the amount of mass an object has. This equation is used because acceleration is directly proportional to its net force. It is the opposite for acceleration and mass because the two are inversely related. If the mass is doubled, the acceleration must be one-half as much. This law provides the reasoning for the fashion in which objects react when the forces are unbalanced. |
