Adding Items to a Shopping Cart to Increase Inertia

Inertia can be defined as the tendency of an object to continue its state of motion or remain at rest unless acted upon by an external force. In the case of a shopping cart, adding items to it increases its mass, which in turn increases its inertia.

Sir Isaac Newton's first law of motion, known as the law of inertia, states that an object in motion will stay in motion, and an object at rest will stay at rest unless acted upon by an external force. The inertia of a shopping cart is influenced by its mass; the more items added to the cart, the greater its tendency to stay at rest.

By increasing the quantity of matter in the shopping cart, the inertia of the cart also increases. This means that the cart will be more resistant to changes in its state of motion, making it harder to move or stop once in motion.
