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. It is approximately 9.8 m/s² on Earth.
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 into the formula: F = 3 kg * 9.8 m/s².
Step 5: Calculate the result: F = 29.4 N.
Step 6: Round the answer to a reasonable approximation, which is about 30 N.
Force of 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.
