A 15 kg object is dropped from a height. What is the force acting on it due to gravity? (2023)
Correct Answer: 150 N
Step 1: Identify the mass of the object. In this case, the mass is 15 kg.
Step 2: Identify the acceleration due to gravity. 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: Substitute the values into the formula: F = 15 kg * 9.8 m/s².
Step 5: Calculate the force: F = 147 N.
Step 6: Round the answer if necessary. Here, 147 N can be rounded to 150 N.
Force due to Gravity – This concept involves calculating the gravitational force acting on an object using the formula F = mg, where m is the mass and g is the acceleration due to gravity.
