5. In the presence of no other outside forces, an object placed under motion will continue to move forever in that same direction

Question

A) True
B) False

6. Which of the following is an example of Newton's First Law?
A) A stationary book on the table must be picked up in order for it to move
B) A baseball hits collides with a fence and they exchange forces
C) Increasing the mass on an object experiencing the same force would decrease the acceleration
D) A rocket made with lighter composite materials will accelerate faster than a heavier one

Answer 1

5. A) True
   In the presence of no other outside forces (no net external force), an object in motion will continue to move in a straight line at a constant speed—this is a statement of Newton's First Law of Motion.

6. A) A stationary book on the table must be picked up in order for it to move
   This statement exemplifies Newton's First Law, which states that an object at rest will remain at rest unless acted upon by an external force. The other options relate to different concepts in physics.
