Question

According to Newton's first law of motion, what happens to a marble traveling in a straight line on a flat hardwood floor that goes on forever?
Question Options:

The force applied by the floor to the marble will cause it to roll backward at the same speed it was moving forward.


A force applied by the hardwood floor will oppose the motion of the marble, causing the marble to slow to a stop.


Gravity will cause the marble to stop after 6ft.


The marble will continue to roll along the hardwood floor at the same speed in the same direction 20 more seconds.

Answer 1

According to Newton 's first law of motion, which states that an object in motion will keep on moving unless an external balance is applied to it. The solution is the last option, the marble will continue to roll along the hardwood floor at the same speed in the same direction for 20 more seconds.

Answer 2

A force applied by the hardwood floor will oppose the motion of the marble, causing the marble to slow to a stop.

This is the correct answer. gravity will cause it to slow down as well as the friction of the floor.
