Yes, unbalanced forces cause acceleration. According to Newton's second law of motion, an unbalanced force acting on an object will cause it to accelerate in the direction of the force. This principle is fundamental in understanding how objects move.

FAQs & Answers

  1. What happens when forces are balanced? When forces are balanced, there is no change in the object's motion, meaning it remains at rest or moves with constant velocity without acceleration.
  2. How does Newton's second law relate force and acceleration? Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
  3. Can acceleration occur without an unbalanced force? No, acceleration only occurs when there is an unbalanced force acting on an object, causing it to change its velocity.
