Question
A box is on an inclined plane not moving. Someone touches it and it starts to slide down at a constant speed until it reaches the bottom. Why did it not stop?(1 point)
Responses
Static friction was decreased by the force from the touch, and the box was able to move.
Static friction was decreased by the force from the touch, and the box was able to move.
The net force on the box before the touch was less than the net force after the touch.
The net force on the box before the touch was less than the net force after the touch.
Static friction was keeping the box in place, but once it was moving, kinetic friction was not enough to stop it.
Static friction was keeping the box in place, but once it was moving, kinetic friction was not enough to stop it.
The force of gravity was increased by the force of the touch, and this increase did not end until the box reached the bottom.

The best response to the question is:
**Static friction was keeping the box in place, but once it was moving, kinetic friction was not enough to stop it.**
When the box was initially at rest on the inclined plane, static friction was able to balance out the gravitational component pulling it down the incline, preventing it from moving. Once it was touched and began to slide, the static friction was overcome, and the box transitioned to kinetic friction. Kinetic friction is typically lower than static friction, allowing the box to continue sliding down the incline at a constant speed, as the force of kinetic friction was not sufficient to bring it to a stop.
