Item FM101001: If an object is moving forward, and a force pushing it backward is greater than a force pushing forward, the object will slow down, stop, and then begin to move faster and faster in the opposite direction.
What will happen to an object that is moving forward if a force pushing it backward is greater than the force pushing it forward?
- The object will move at constant speed for a while and then slow down and stop.
- The object will slow down for a while and then move at a slower constant speed.
- The object will slow down, stop, and then begin to move faster and faster in the opposite direction.
- The object will slow down, stop, and then begin to move at a constant speed in the opposite direction.
