Questions & Step-by-Step Solutions

If a 3 kg object is in free fall, what is the force acting on it due to gravity?
  • Step 1: Identify the mass of the object. In this case, the mass is 3 kg.
  • Step 2: Know the acceleration due to gravity. On Earth, this is approximately 9.8 m/s².
  • Step 3: Use the formula for force due to gravity, which is F = mg, where F is the force, m is the mass, and g is the acceleration due to gravity.
  • Step 4: Plug in the values: F = 3 kg * 9.8 m/s².
  • Step 5: Calculate the force: F = 29.4 N.
  • Step 6: For simplification, you can round 29.4 N to approximately 30 N or 9 N, depending on the context.
  • Force due to Gravity – The force acting on an object due to gravity is calculated using the formula F = mg, where m is the mass of the object and g is the acceleration due to gravity.
