  Newton's Second Law states that the acceleration produced by a net force on a body is directly proportional to the magnitude of the net force. It is in the same direction as the net force and is inversely proportional to the mass of the body. The acceleration of the object depends on two things. One is the net force acting on the object and the other is the mass of the object. In Newton's second law there is an effect on force and an effect on mass. An object will only accelerate if there is a net force acting on it.

The image is from Nasa.This is a picture of Newton's Second Law. The A is the action that pushes on the rocket. Then when the rocket takes off it has a greater reaction.

 

 

 

The picture is from Nasa.This shows the second law of motion with a rocket ship taking off.

This is the air pushes out and the object moves forward.
           The force deals with the acceleration which increases as you apply more force on the object. The object moves in the direction that you push or pull it in. The first part of acceleration dealing with force indicates that if you were to apply twice as much net force then you would get twice the acceleration too. The same is fore three times as much net force then three times as much acceleration. In this case the objects force is directly proportional to the net force acting on it. Objects with different mass, for example a car and a dog the effect of the force is not the same. The heavier object will resist more because it has more mass. This is when you double the mass you get half the acceleration. This is called inversely proportional.
