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
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.
The increase in ease of pushing or pulling the trolley as Lance stacks books on shelves can be explained by Newton's first law of motion, also known as the law of inertia. According to this law, an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.
When Lance stacks books on shelves, he is increasing the mass of the trolley, thereby increasing its inertia. As a result, the trolley resists changes in its state of motion, making it easier for Lance to push or pull it. The increased mass of the trolley leads to an increase in its resistance to acceleration and deceleration, allowing a smoother movement for Lance.
The increase in ease of moving the trolley as Lance stacks books can be explained by Newton's First Law of Motion, which is also known as the law of inertia.
According to this law, an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. In other words, an object will keep doing what it is doing unless there is a force that changes its state of motion.
Initially, when the books are on the trolley, they provide resistance to Lance's efforts to push or pull it. This is because the books have mass, and it requires a force to accelerate or decelerate them. As a result, Lance needs to exert more force to overcome the resistance and move the loaded trolley.
However, as Lance continues to stack the books onto the shelves, the mass of the trolley decreases. Consequently, the resistance to motion also decreases, making it easier for Lance to push or pull the trolley. This is because the force required to accelerate or decelerate an object is directly proportional to its mass.
Thus, the increase in ease of moving the trolley as Lance stacks books is an example of Newton's First Law of Motion, which explains how an object's mass affects the force required to change its motion.
