Newton's second law basically states that the acceleration and speed of an object, animate or inanimate, depends on the net force acting upon the object and the mass of the object.
*** For example, it is easier for a strong adult to push a full shopping cart than it is for a baby to push the same cart. (This is depending on the net force acting on the object.) Also, it is easier for a person to push an empty shopping cart than a full one. (This is depending on the mass of the object.)
*** Another example is a train wreck. If a train hits another train of equal force and speed, they will both go the same distance and feel the same force. But if the first train is hooked to a second, the single train will go twice the distance of the double train and will feel twice the force. (This example pertains to both net force and mass.)
