Questions & Step-by-Step Solutions
A 2 kg object is in free fall. What is the net force acting on it?
Correct Answer: 19.6 N
Step 1: Identify the mass of the object. In this case, the mass is 2 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 = 2 kg * 9.8 m/s².
Step 5: Calculate the result: F = 19.6 N.
Step 6: Conclude that the net force acting on the object is 19.6 N.
Newton's Second Law – 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 the force due to gravity acting on an object, calculated as the product of mass and gravitational acceleration.
