  1. Newton’s Laws of Motion Force & Acceleration
  2. Learning Objectives Analyze relationships between forces and motion Calculate the effects of forces on objects Newton’s Laws of Motion
  3. Newton’s second law of motion – states that the acceleration (a) of an object is directly related to the net force on the object (Fnet) and inversely related to the mass of the object (m) Units of newtons can be broken down using Newton’s second law Force & Acceleration
  4. Force & Acceleration Example Ex) A 91 N force causes an object to accelerate at 0.76 m/s2. What is the mass of the object? Strategy Given and unknown Formula Conversions needed? Intermediates needed? Solve Does the result make sense? No. No. so Yes.
  5. Force & Acceleration Example Ex) A 250 N net force is applied to a 72 kg object. What is the acceleration of the object? Strategy Given and unknown Formula Conversions needed? Intermediates needed? Solve Does the result make sense? No. No. so Yes.
  6. Force & Acceleration Example Ex) A 5.0 kg object is traveling at a constant velocity of 3.2 m/s. What is the net force acting on the object? Strategy Given and unknown Formula Conversions needed? Intermediates needed? Solve Does the result make sense? No. No. Yes.
