How to Calculate Acceleration with a Net Force of 12N on Combined Masses

Learn to calculate acceleration using Newton's second law with a 12N force on a 9kg combined mass.

0 views

To determine the acceleration when a 12N net force is applied to both a 3kg object and a 6kg object, first combine their masses (3kg + 6kg = 9kg). Then, use Newton's second law: acceleration = net force / total mass. So, acceleration = 12N / 9kg = 1.33 m/s^2.

FAQs & Answers

  1. What is Newton's second law? 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.
  2. How do you combine masses in physics? To find the total mass, simply add the individual masses together.
  3. What is acceleration? Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).
  4. How do you measure net force? Net force is determined by vector addition of all individual forces acting on an object, resulting in a single resultant force.
