A person applies the same 100 N force to a large piano and a small book. Which object will experience a greater change in motion?

Question

A
The book

B
The piano

C
They will experience the same change in motion.

D
More information is required.

Answer 1

The correct answer is:

A. The book

This is because the change in motion of an object (its acceleration) is determined by Newton's second law of motion, which states that \( F = m \cdot a \) (force equals mass times acceleration). Given that the same force (100 N) is applied to both the large piano and the small book, the object with the smaller mass (the book) will experience a greater acceleration (change in motion) compared to the larger mass (the piano). Hence, the book will experience a greater change in motion.
