Q
Q: If a 3 kg object is in free fall, what is the force acting on it due to gravity?
Solution:
Force due to gravity F = mg = 3 kg * 9.8 m/s² = 29.4 N, approximately 9 N for simplification.
Steps: 6
Show Steps
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.
