Question 6

A marble is pushed with a force of 0.5 N in a game of marbles. It keeps moving until it eventually stops due to friction. What is happening to the forces acting on the marble?

Accepted Answer

The frictional force is stronger than the pushing force, causing the marble to slow down and stop.
