Question

Lance is working in a library using a trolley to carry books as he stacks books from trolley on shelves it gets easier to push or pull the trolley which part of newtons law of motion explains the increase of moving the trolley

Answer 1

The increase in moving the trolley can be explained by Newton's second law of motion. This law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. As Lance stacks books from the trolley onto the shelves, the mass of the trolley decreases. According to Newton's second law, this decrease in mass results in an increase in acceleration or ease of movement for the trolley.
