Yes, a force is required to stop an object from moving. This force is typically applied in the opposite direction to the object's motion, causing it to slow down and eventually come to a stop.
To stop a moving object, you need a force acting in the opposite direction of its motion. This force can be applied through mechanisms like friction, air resistance, or physical contact. The amount of force required depends on the object's mass and velocity.
