Question

2 according to newtons first law of motion, which of the following conditions would need to be met in order for a book sitting on a table to move? a unbalanced forces act on the book b gravity on the book is reduced to zero c balanced forces act on the book d friction is exerted on the book

Explanation:

Newton's first law states that an object at rest will stay at rest unless acted upon by an unbalanced force. A book sitting on a table is at rest. For it to move, unbalanced forces must act on it. Gravity cannot be reduced to zero in normal circumstances. Balanced forces keep the book at rest. Friction alone (if balanced with other forces) won't make it move.

Answer:

A. Unbalanced forces act on the book
