The correct answer is: A greater force is needed to move an object with a greater mass.
The correct answer is: A greater force is needed to move an object with a greater mass.
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In simpler terms, this means that the force needed to accelerate an object depends on both the mass of the object and the desired acceleration.
In the case of pushing an empty cart versus a full one, the mass of the cart affects the force required to move it. An object with greater mass (like a full cart) will require a greater force to achieve the same acceleration as an object with lesser mass (like an empty cart). This is because the mass of the cart resists changes in its motion, and as a result, it takes more force to overcome that resistance and move the heavier load.
To summarize, Newton's second law of motion explains that the greater the mass of an object, the greater the force required to accelerate it. Thus, it is easier to push an empty cart because it has less mass compared to a full cart, and therefore requires less force to be moved.
