Question

Four boxes are sliding with a constant speed before each box experiences an unbalanced force of 8 N. Which box would experience the greatest acceleration when the unbalance force is applied?

Answer 1

From Newton's second law of motion, we know that acceleration (a) is directly proportional to the force (F) acting on an object, i.e., a = F/m, where m is the mass of the object.

Since all four boxes experience the same unbalanced force of 8 N, the box with the smallest mass (m) will experience the greatest acceleration. This is because a smaller mass will result in a larger acceleration for the same force.

Therefore, the box with the smallest mass will experience the greatest acceleration when the unbalanced force is applied.
