Newton’s Second Law states that the acceleration and speed of an object depends on the net force acting upon the object and the mass of it. In a supermarket, when adults push the shopping cart, it seems easier for them than if a child was pushing it. This shows that the more mass a person has, the faster and easier it will be to do work. Another example is the variation of weight the shopping cart has. The more weight, it has the harder it is than if you were to take everything out and push it around.
