The first statement, "A force is changing the motion of the bus," is the most accurate description of the situation. When the driver applies the brakes, it creates a force that opposes the forward motion of the bus, causing it to slow down and eventually come to a stop.
are you sure
Yes, I am sure. When the bus stops, it is because a force is applied in the opposite direction to its motion, which causes it to decelerate and come to a stop. This force is exerted by the brakes, which create friction between the brake pads and the wheels, resulting in a force that opposes the forward motion of the bus. Therefore, the statement "A force is changing the motion of the bus" is the most accurate description of the situation.
