Questions & Step-by-Step Solutions

A 50 kg object is in free fall. What is the net force acting on it?
  • Step 1: Identify the mass of the object. In this case, the mass is 50 kg.
  • Step 2: Understand that the object is in free fall, which means the only force acting on it is gravity.
  • Step 3: Use the formula for weight (which is the force due to gravity): F = mg, where F is the force, m is the mass, and g is the acceleration due to gravity.
  • Step 4: Substitute the values into the formula: F = 50 kg * 9.8 m/s².
  • Step 5: Calculate the result: 50 kg * 9.8 m/s² = 490 N.
  • Step 6: Conclude that the net force acting on the object is approximately 490 N.
  • Newton's Second Law of Motion – The net force acting on an object is equal to the mass of the object multiplied by the acceleration due to gravity.
  • Weight Calculation – Weight is calculated using the formula F = mg, where m is mass and g is the acceleration due to gravity.
