Give some examples for newton's 2^nd law of motion

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) .

hope this helps:)
