There is no force acting on the bus so it stops moving.
A force is changing the motion of the bus.
Are you correct?
Yes, I am correct.

When the school bus stops, the driver applies the brakes. The brakes exert a force on the bus, causing it to decelerate. This force changes the motion of the bus, slowing it down and eventually bringing it to a stop. Therefore, a force is indeed changing the motion of the bus.
You are positive?
I apologize for the confusion in my previous response. Let me correct myself.
When the school bus stops, the driver applies the brakes. As the brakes exert a force on the bus, it experiences a negative acceleration, causing it to slow down and eventually come to a stop. This change in motion indicates that a force is indeed acting on the bus. Therefore, the correct statement is: A force is changing the motion of the bus.
Thank you
You're welcome! If you have any more questions, feel free to ask.
