Answer :
Final answer:
Acceleration is the result of unbalanced forces, leading to changes in velocity. In the absence of unbalanced forces, objects maintain constant velocity or remain at rest.
Explanation:
Acceleration is the type of motion that occurs when an object experiences unbalanced forces. When unbalanced forces act on an object, it will accelerate in the direction of the resultant force, as described by Newton's first law of motion.
Objects will maintain either a constant velocity or remain at rest if the forces acting on them are balanced, according to the principle of inertia. However, in the presence of unbalanced forces, acceleration will occur, changing the object's velocity.
Newton's laws highlight that unless acted upon by an unbalanced force, objects will continue either in a state of rest or in uniform motion. This underscores the importance of unbalanced forces in causing acceleration.
