A. A shopping cart accelerates when it is pushed.
This scenario best demonstrates an example of Newton's first law of motion, which states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In this case, the shopping cart is at rest until a force is applied to it by being pushed, causing it to accelerate.
