When an unbalanced force acts on an object the motion of the objects changes. Sometimes the object continues to move at the same speed. When that happens, what is it that changes?
a)direction; b)friction; c)mass; d)weight
When an unbalanced force acts on an object, the motion of the object changes. Sometimes, despite the unbalanced force, the object continues to move at the same speed. In this scenario, the object continues moving in a straight line, which means that the object's direction does not change.
To determine what changes in this situation, we can consider the other options: friction, mass, and weight.
a) Friction: Friction is a force that opposes the motion of an object. However, the question states that the object continues to move at the same speed, indicating that friction is not the factor causing the change.
b) Mass: Mass is a measure of the amount of matter in an object. It represents the object's inertia and is responsible for resisting changes in motion. However, the question states that the object continues to move at the same speed, which indicates that mass is not the factor causing the change.
c) Weight: Weight is the force exerted on an object due to gravity. It depends on the mass of the object and the acceleration due to gravity. Since the question implies that the object continues to move at the same speed, weight is not the factor causing the change either.
Therefore, the correct answer is a) direction. When an unbalanced force acts on an object, the object's motion changes, but if the object continues to move at the same speed, it means that only its direction changes while its speed remains constant.
